4. Each boy on the hike is carrying 1.5 liters of water. If there are 15 boys, how many total liters of water are they carrying?
maria [59]

Answer:

22.5 liters

Explanation:

Hello!

If each boy on the hike is carrying 1.5 liters of water, and there are 15 boys, we simply multiply the two terms.

Multiply:

  • liters * boys = total liters
  • 1.5L * 15 = total liters
  • 22.5 total liters

They are carrying 22.5 liters of water in all.
