Subtracting mixed fractions

In today's post, i will share with you the concept of subtracting mixed fractions. First let's know what is a mixed fraction. A mixed fraction is that where a whole number and a fraction is mixed.

In order to subtract mixed fractions, first the mixed fraction is to be converted to improper fraction and then the subtractions should be operated. In case the denominators are different, LCM should be found out of the two denominators and a common denominator should be taken. There after subtract fractions should be performed.

Also one can avail to an online tutor for more help. This help can be gained not just for fractions but one can opt for free algebra tutoring and geometry tutoring online as well.

Next time, we will move on to some other concepts, till then practice problems based on this concept and gain a proper help.

Familiarization with math

Introduction to linear relationships online help:

Linear relationship is nothing but the function varies directly with the input. The graph of linear relationship is a straight line. Linear relationships include linear equations and systems of linear equations with some unknowns. All the points lie on a line then such a model is called a linear relationship because it represents a straight line relationship between the points. Through the online help, student can get clear idea about how to solve linear relationships. Now, we are going to see some of the problems on linear relationships online help.

Example :

Solve the linear relationship in the equation: -2(y + 3) = y + 9

Also find more help linear programming example

Solution:

-2(y + 3) = y + 9

First we need to eliminate the parentheses

-2y - 6 = y + 9

Add 6 to both sides of the equation

-2y - 6 + 6 = y + 9 + 6

-2y = y + 15

Subtract y on both sides of the equation

-2y - y = y + 15 - y

-3y = 15

Divide-3 on both sides of the equation Learn solving math Online

y = -5

y = -5 is the solution to the given equation.

Introduction to help with algebra 2:-

In this topic we are going to discuss about the help in algebra 2 concept. It different kinds of problem handle on this article. It is cluster of expression & arithmetic equation also process here. It simpler equation problems also show on this article. These articles help to improve the algebra 2 skills also. Algebra 2 basic chapter problem shown on below.

Help algebra 2 problem :-

Solve the help algebra 2 equation.

-3(x + 2) = x + 12

Solution:

-3(x + 2) = x + 12

Multiply factors in left term

-3x - 6 = x + 12

Add 6 to both sides

-3x - 6 + 6 = x + 12 + 6

Grouping the above terms

-3x = x + 18

Subtract x to both sides

-3x - x = x + 18 -x

Group like terms simplifying expressions calculator

-3x = 18

Multiply both sides by -1/3

x = -18/3

x = -2 is the solution to the given equation Learn solving math Online

Introduction to mixed fraction calculator :

Fractions are most important part of mathematics. Daily people use this fractions in day-today life. Mixed fractions look like a (b /c) form. Decimals calculator displays point values and rounded values. This topic we will discuss about the conversion of mixed fractions to decimals values.

The types of fractions:

Mixed fractions to decimals calculator :

Convert mixed fraction to decimals: 1(1/2)

Solution:

First we convert mixed fraction to fraction.

[(1 + 2)/2] =3/2

Only few steps here in order to convert 3/2 into a decimal.

  • Now find, that 3/2 is the same as 3 divided by 2.
  • So we'll write the 3 as 3.0 instead (a 3 with 1 zero after the decimal point).
  • Now, we just find the fraction: divide 3.0 by 2.
  • Do you know how to add mixed fractions

=3.0/2

=1.5

3/2 written as a decimal to 3 decimal place is 1.5.

Math Question and Answer

Introduction to conditional probability examples

When we deal with 2 events, A and B , sometimes these events are so related to each other , that the probability will depend on whether the other event has already occurred.It can be defined as the probability of given event that another event has already occurred.

Let’s consider an example for Conditional probability:

If a player needs to pick 2 cards of the same suit to win, out of 52 cards there can be 13 cards in each suit.Find mathematics form 3. If the player1 Picks a heart, and the player wishes to draw a second heart. If one heart has already been selected, then we only have 12 hearts remaining out of 51 cards.

So Familiarization with math is the conditional probability P = 12/51....

Growing up with Mathematics

Let us learn more on online Probability calculator:

It is used to derive the basic statistic probabilities calculation online. also mainly works out with odds i.e. the probability questions like exactly, at least etc. It solves one event and also multiple event probability problems.

Example: Find the probability to get a tail when we toss a coin Number of sides on coin = 2 (sample space)

It only has one tail on a coin

The probability of showing tail = 1/ 2.

Types : Normal probability calculator

It is used to calculate the normal distribution variables. Usually probability calculator calculates the normal Probability i.e. the number of result of an event out of possible outcomes. ‘P’ = Number of possible results / Sample space find Probability calculator online

Example:A bag consists of 6 black balls, 4 blue balls and 3 grey balls; a ball is picked up at random. Find the probability to select a black ball.

Given that Black balls = 6

Blue balls = 4

Grey balls = 3

Total number of balls = 6 + 4 + 3 = 13

Sample space = 13!/(13 - 1)! = 13

Number of possibilities = 6/(6 - 1)1 = 6

P(B) = 6/13

Therefore probability is 6/13.

Binomial probability calculator

It is used to find cumulative and individual binomial probabilities. A Binomial distribution is the probability distribution. It is associated with the number of Profit in a Binomial Experiment. It can be used for Solving or creating new binomial probability problems learn Math at your fingertips.

linear programming help

Introduction to linear programming problems:

Linear programming is the process which helps in decision making in business for obtaining the maximum or minimum value of a linear expression, subject to satisfying certain given linear inequalities.

The linear expression is called as an objective function and the linear inequations are known as linear constraints. , linear constraints help in business or industry that one want to make the best use of our limited resource like money, labour, time materials, etc. The limitation on the resource can be expressed in the form of linear inequations, known as linear constraints. This topic will certainly help you to learn about linear programming.


Help with Linear Programming

Objective Function:

A linear function of the involved variables, which one want maximize or minimize, subject to the given linear constraints, is known as an objective function also need help with mean and standard deviation

Optimal value of an objective function:

The maximum or minimum value of an objective function is called as its optimal value.

Feasible solution:

A set of value the variable satisfying all the constraints is called as feasible solution of system of inequation. for more help in Statistics
