Prove that your recipe makes exactly 10 cups. • Explain the most efficient method for measuring each ingredient using only
the following two measuring cups:
1/3
cup and
1/4
cup. You can use one or
both of the measuring cups

Use both measuring cups 16 times and then use the cup to measure twice for exactly 10 cups.

Step-by-step explanation:

When working with fractions, I like to make the denominators the same first.

cup = cup

cup = cup

10 cups = cups

Now, for the most efficient method, it would be reasonable to use both cups so that it is quicker.

1 scoop using both cups: + = cup in total

No. of scoops using both cups: ÷ = 16 R

You know that using both cups, you can scoop 16 times with a remainder of . You cannot scoop using both cups without the remaining left to scoop, so you have to use only one cup to scoop. The bigger cup is the cup, so I will use that one to scoop the remaining .

No. of scoops using the   cup: ÷   = 2

Overall, you will use both cups together for 16 times, then use the cup twice.
