Question

Explain how to use repeated addition to write the multiple of a fraction as a whole number and a unit fraction.

Answer 1

Lets say you have 5x5. you would just add 5+5+5+5+5. To get a whole number for a fraction you have to do this. lets say you have 8/8 that would be equal to 8 circles and eight of those circles would be shaded in. 8/8 is one whole also 7/1 is a whole. It all depends on the problem you are trying to figure out

Answer 2

Multiplication is the same as repeated addition so let us take an example for a better understanding

2/3 * 4

Looks more like this

2/3 + 2/3 +2/3 = 2/3 = 8 /3

(If you add them up, we will get the same answer if we multiply it)

Same as 2/3 *4/1 = 8/3

On the other hand if you have whole numbers that you need to solve like 3*4 this means that 3 is added 4 times

3 + 3+ 3+ 3 = 12

Which would be the same thing as

3*4 = 12
