Answer 1

4 9/20

Explanation:

We are subtracting since he gave them candy

Let's get the whole numbers out of the way

7 - 2 = 5

Now we subtract the fractions

1 / 4 - 4 / 5. We need to find the LCD (Lowest common denominator) of the fractions which is 20 because 4 x 5 = 20 and 5 x 4 = 20

Rewriting the denominators and numerators:

Since we multiply 4 by 5 to get 20 we'll have to do the same to the numerator (1)

1 x 5 = 5

Now we do the same to 4/5. 5 x 4 = 20 and 4 x 4 = 16.

New fractions

5/20 - 16/20 switch it 16 / 20 - 5 / 20 = 11/20 and we get the answer from subtracting the whole numbers by 11/20 (the answer we got from subtracting fractions) 5 - 11/20 = 4 9/20
