a guy is 1/2 inches tall other guy is 7/8 how much taller is the other guy

To find out how much taller the other guy is, we need to subtract the height of the first guy from the height of the second guy.

Height of the second guy = 7/8 inches
Height of the first guy = 1/2 inches

To subtract fractions, we need a common denominator. The common denominator for 2 and 8 is 8.

Height of the second guy - Height of the first guy = (7/8) - (1/2)
= (7/8) - (4/8)

Now, we can subtract the fractions:
= (7 - 4)/8
= 3/8

Therefore, the second guy is 3/8 inches taller than the first guy.
