Step by Step Explanation

I used the same method with all 6 questions, I had to tweak it slightly for the last 3 as they were mixed fractions.

For the first 3 questions, I used the number you had to make and multiplied it by the denominator. Let's use the first questions as an example.

We need to make 7 by adding something to 27/4. I multiplied 7 by 4 in order to get 28.

This means your goal is to get to 28/4.

The difference between 28/4 and 27/4 is 1/4. Meaning you only have to add 1/4 in order to make 7.

For the last 3 questions I first sorted the fractions out. Let's use the first question again on the right side as an example.

I made 5 a top heavy fraction by first multiplying 5 by 8, which makes 40. I then added 40 to 7 making 47. Now the fraction is 47/8.

Now that we have our top-heavy fraction we do the same as last time. We need to make 7. So we multiply 7 by 8 and that makes 56. The difference between 56 and 47 is 9. So we need 9/8 in order to get to 56/8. We need a mixed fraction so 9/8 becomes 1.

I hope this helps, if this was confusing don't be afraid to ask questions.
