solution

Start by listing the information from the problem.

Rose uses 6 fluid ounces of marinade for every pound of chicken. You can write this rate as a fraction:
6
fl oz
1
l
b
.
Rose plans to grill 4 pounds of chicken.

The problem asks how much marinade Rose needs. So, multiply the amount of marinade she needs for 1 pound of chicken by 4 pounds. The result will be in fluid ounces since the units of pounds cancel out.

fl oz

Now you know Rose needs 24 fluid ounces of marinade but the problem asks about

cups.

So, convert the fluid ounces to cups.

There are 8 fluid ounces in 1 cup, so multiply by

fl oz

The result will be in cups since the units of fluid ounces cancel out.
