Question

The gas tank in Sharon’s car can hold up to 16.5 gal of gas. About how many liters of gas can the tank hold? 1 L≈1.06 qt
3.9 L
4.4 L
62.3 L
70.0 L

Answer 1

Most people have trouble deciding on what conversion factor to use. If there you use one conversion factor, and you get something like this:

(gal^2)/qt

Then you know that you used the wrong conversion factor. ALWAYS remember to multiply and divide your units. If you don't, you will not know whether or not you got what you were looking for.
