How do i my child when i was not taught this way

QUESTION 1

The first step here would be to convert both the mixed fractions into an improper fraction. This will make it easier to subtract both fractions. To convert the fraction, we simply need to multiply the denominator by our whole number, then add our answer to the numerator.

4  = 

1  =  

Now that both our fractions are converted, we can subtract straight across. Please remember that we do not subtract the denominator.

-  = 

Now we have our improper answer. We will make it proper (mixed fraction).

2 

Since our answer cannot be simplified, that is our final answer.

QUESTION 2

The first step here would be to convert both the mixed fractions into an improper fraction. This will make it easier to subtract both fractions. To convert the fraction, we simply need to multiply the denominator by our whole number, then add our answer to the numerator.

9  = 

3  = 

Now that both our fractions are converted, we can subtract straight across. Please remember that we do not subtract the denominator.

-  = 

Now we have our improper answer. We will make it proper (mixed fraction).

5 

Since our answer cannot be simplified, that is our final answer.
