Question

Your puppy weighed 2 1/2 lb last week. This week it weighs 7 1/4lb. How much weight has the puppy gained? A) 9 3/4 B) 3/4 C) 4 3/4 D) 7 1/2

Answer 1

Hello!

You have to subtract 7 1/4 and 2 1/2. First change both to a common denominator to make it easier.

Common denominator: 4

$2 \frac{1}{2} = 2 \frac{2}{4}$

$7\frac{1}{4} = 7\frac{1}{4}$

$7 \frac{1}{4} - 2 \frac{2}{4} = 6\frac{5}{4} - 2 \frac{2}{4} = 4 \frac{3}{4}$

Answer ⇒ $4 \frac{3}{4}$

Answer 2

The answer to your question is C) $4 \frac{3}{4}$

7 - 2 = 5. Then you're left with $\frac{1}{4} - \frac{2}{4}$, which is $\frac{3}{4}$.
