Example 7.55 from Prealgebra, 7.5 Systems of Measurement

Systems of Measurement: example 7.55

Lee’s water bottle holds $500$ mL of water. How many fluid ounces are in the bottle? Round to the nearest tenth of an ounce.

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

500 mL

Multiply by a unit conversion factor relating mL and ounces. $500 mL \cdot \frac{1 fl oz}{30 mL}$

Simplify. $\frac{500 fl oz}{30}$

Divide. $16.7 fl. oz.$

The water bottle holds 16.7 fluid ounces.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

How many quarts of soda are in a $2-liter$ bottle?

How did it go?
