Question

which weighs more: a watermelon that weighs 7.5 kilograms or a baby that weighs 12 pounds? (note: 1 pound is about 0.45 kilograms.) a. watermelon b. baby c. they weigh the same

Explanation:

Step1: Convert baby's weight to kg

We know 1 pound = 0.45 kg, so for 12 pounds, weight in kg is $12\times0.45 = 5.4$ kg.

Step2: Compare weights

Watermelon is 7.5 kg, baby is 5.4 kg. Since $7.5>5.4$, watermelon weighs more.

Answer:

A. Watermelon
