Question

Five hummingbirds drink 7.5 ounces of sugar water a day. How much sugar water is needed for 14 hummingbirds?

Answer 1

First, divide 7.5 by 5 to find out how much sugar water is needed for each bird. 
Each bird needs 1.5 ounces per day. 
Then just multiply that by 14 to get 15.5 ounces of sugar water.
Hope this helps!

Answer 2

Since 5 hummingbirds drink 7.5 ounces, we have to figure out how many ounces goes to only one. 

You should divide 7.5 by 5, and that equals 1.5

Then you're going to multiply 1.5 by 14 because there are 14 hummingbirds

1.5 * 14 = 21

21 ounces of sugar water is needed for 14 hummingbirds.
