Gary is 8 3/4 years old. His brother is 3 7/12 years younger than he is. How many years old is Gary’s brother?(1 point)
To find out how old Gary's brother is, we'll subtract 3 7/12 from 8 3/4.
First, we need to convert 8 3/4 and 3 7/12 to a common fraction:
8 3/4 = (8 * 4 + 3)/4 = 35/4
3 7/12 = (3 * 12 + 7)/12 = 43/12
Next, we'll subtract 43/12 from 35/4:
35/4 - 43/12 = (35 * 3) / (4 * 3) - 43/12 = 105/12 - 43/12 = 62/12
Lastly, let's simplify 62/12:
62/12 = (2 * 31) / (2 * 6) = 31/6
Therefore, Gary's brother is 31/6 years old, which is approximately 5 1/6 years old.
