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

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:

Ben grows 5/8 feet more

Step-by-step 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 \(4\frac{3}{4} =\frac{19}{4}\)

13th birthday , Ben was \(5\frac{3}{8} =\frac{43}{8}\)

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

\(\frac{19}{4} -\frac{43}{8}\)

To subtract , make the denominators same . LCD is 8

\(\frac{43}{8}-\frac{19}{4}\)

\(\frac{43}{8}-\frac{38}{8}\)

\(\frac{5}{8}\)

So Ben grows 5/8 more
