15 blocks weigh 80 grams. How many grams will 4 blocks weigh?

15 blocks = 80 grams 1 block = \(\frac{80}{15}\) grams 4 blocks = \(4 \times \frac{80}{15}\) grams

Solution

To find out how many grams 4 blocks will weigh, we can set up a proportion based on the information given: 15 blocks weigh 80 grams. First, find the weight of 1 block: \[ \frac{80 \text{ grams}}{15 \text{ blocks}} = \frac{80}{15} \approx 5.33 \text{ grams/block} \] Next, calculate the weight of 4 blocks: \[ 5.33 \text{ grams/block} \times 4 \text{ blocks} = 21.32 \text{ grams} \] Therefore, 4 blocks will weigh approximately 21.32 grams.
