Question

I always take my water bottle on a hike. I drink 1/2 a liter of water for every mile. Yesterday I hiked 3/4 of a mile, what fraction of water did I drink?

Answer 1

Remember that when you read the word "of" in a math problem it means to multiply. Therefore, if 1 mile = 1/2 liter of water, then 3/4 "of" 1 mile = 3/4 "of" 1/2 liter:

3/4(1) = 3/4(1/2) = 3/8

So, the answer is 3/8 of a liter of water.

Hope this helps!
