Susie grew 7/8 of an inch last year while her brother Tommy grew 3/8 of an inch how many more inches did Susie grow then Tommy

To find out how many more inches Susie grew than Tommy, we need to subtract Tommy's growth from Susie's growth.

Susie grew 7/8 of an inch.
Tommy grew 3/8 of an inch.

The difference in their growth is: 7/8 - 3/8

To subtract the fractions, we need to find a common denominator, which in this case is 8.

7/8 - 3/8 = (7-3)/8
= 4/8
= 1/2

Therefore, Susie grew 1/2 inch more than Tommy.

To find out how many more inches Susie grew than Tommy, we need to subtract the growth of Tommy from the growth of Susie.

Growth of Susie = 7/8 inch
Growth of Tommy = 3/8 inch

Subtracting the growth of Tommy from the growth of Susie:
Growth of Susie - Growth of Tommy = (7/8) inch - (3/8) inch

To subtract fractions with the same denominator, we subtract only the numerators and keep the denominator the same:
(7 - 3)/8 inch

Simplifying the numerator:
4/8 inch

We can simplify the fraction 4/8 by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(4 ÷ 4)/(8 ÷ 4) inch
1/2 inch

Therefore, Susie grew 1/2 inch more than Tommy.
