Question

Ubtract. - B the model to help

Answer 1

As you can see in the model

`(1)/(2)=(4)/(8)`

Then

`(5)/(8)-(1)/(2)=(5)/(8)-(4)/(8)=(5-4)/(8)=(1)/(8)`

This is the same as if you removed 4 pieces of 1/8 from the 5 pieces of 1/8, resulting in 1 piece of 1/8.

Therefore, the result of the subtraction is

`(1)/(8)`
