Question

One gallon is equal to about 3.785 liters. What is this amount rounded to the nearest tenth? What is the greatesr number of whole liters of water you could pour into one-gallon container wothout overflowing? Explain your answer.

Answer 1

To round to the nearest tenth, examine the hundredths place digit, which is 8. Since this is greater than 5, then you round up. In other words, this amount rounded to the nearest tenth is 3.8 L. 

 

Using metric conversion, there are 3.78541 L in 1 gal. Hence, we could pour 3 whole liters into a one-gallon container without overflowing. If we attempted to pour the next whole liter, which is 4, it would be too much.
