Answer 1

1. 3

2. 5

3. 12

Explanation:

1/4=3/12

Answer 2

3/12 = 4/12

or

3/12 = 1/3

being are last boxes to autofill.

Explanation:

1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3

When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.

12 / 4 = 3

we get 3/12

Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12

The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.

As 4/12 = 1/3
