Mixed Numbers

By: Azhar Jamal

A ratio is comparing objects and/or colors. An example of a ratios is shown below.

This ratio shows 5 girls to 15 boys. You can show it as 5:15, 5 to 15 or 5 over 15. Ratios are used to make part-to-part and part-to-whole comparisons.

Related fractions are:Ex

3x3 = 9 the related fraction would be 18/2 that would also = 9

Related fractions all have something in common

They all have the same answer

They can also sometimes be flipped around: EX 2+3=5 switch it around and you get the same answer

Mixed number is when you turn an improper fraction into a whole number like this:

12 is the improper fraction

5 you find something to

multiple 5 by something

which is smaller than 12.

Since 10 is smaller than 12

and is multiple of 5 because 5 x 2 = 10.

and 10 + 2 = 12 since 5 is the dinomintar the whole number has to be 2 because 5 x 2 = 10 and 2 must be the nominator because 10 + 2 = 12.

Notice how The top number is smaller, it is called the numerator.

The bottom number is called the denominator, it is always greater than the numerator.

An improper fraction is a fraction that states how many pieces in each solid and how many pieces all together. For example if you look at the image below you will see that it is the exact opposite of the proper fraction. The denominator can also be the same as the numerator. The seven is stating how many pieces, the four is stating how many pieces in the shape.

notice how the numerator is greater than the denominator

The numerator is always smaller or equal to the denominator.

Percentage is always out of 100.

These are examples of some percentages... In percentage questions you have a grid made of a number of cubes for example: The grid has a hundred cubes and 24 of them are colored or shaded in

that means that the percent is

24%

5 x 2 = 10

10 + 2 = 12

formula

By: Azhar

There are some types of percents

which might be in a shape or for example like this square you would apply the same rules as a grid. You would count the number of squares. Since you know there are 100 squares in a grid you would divide 4 by 100 which gives you 25 because 25 x 4= 100, So each square is 25%

Other Types Of Percent Styles You Might See

By: Azhar

For the different styles off percentages

you apply the same rule:

1. You would count the number of pieces or parts

2. Then you divide the number of pieces or parts to 100

3. Then what your result is that's your percent
