Question

on his twelfth birthday Ben was 4 3/4 feet tall. On his thirteenth birthday Ben was 5 and 3/8 feet tall. How much did Ben grow between his 12th and 13th birthdays? PLZ answer QUICK

Answer 1

Ben grew 5/8 feet.

If he grew from 4 3/4 to 5 3/8, the first thing you want to do is find the common denominator. Now you have:

4 6/8 and 5 3/8

Since you are trying to find the difference, you would take the larger number and subtract the smaller number from it.

5 3/8 - 4 6/8 = 5/8

Answer 2

Ben grows 5/8 feet more

Explanation:

On his twelfth birthday Ben was 4 3/4 feet tall. On his thirteenth birthday Ben was 5 and 3/8 feet tall.

12th birthday , Ben was
`4(3)/(4) =(19)/(4)`

13th birthday , Ben was
`5(3)/(8) =(43)/(8)`

To find the difference in height between 12th and 13th birthday, subtract the heights

`(19)/(4) -(43)/(8)`

To subtract , make the denominators same . LCD is 8

`(43)/(8)-(19)/(4)`

`(43)/(8)-(38)/(8)`

`(5)/(8)`

So Ben grows 5/8 more
