# After you write your recipe, complete the following for your contest entry:

• 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. Note: Depending on the fractions that you chose

for your ingredient amounts, it may not be possible to create each exact

amount using only

1

3

and

1

4

measuring cups. If you need to, you can round

your ingredient amounts using benchmarks and then explain how you would

estimate that amount. For example, if you need

4

7

cup of an ingredient,

4

7

cup is slightly more than

1

2

cup. You could fill up your

1

4

measuring cup twice

to make

1

2

cup of that ingredient, and then add just a tiny bit more to

estimate

4

7

cup.

• Use equations or other models to show how you would measure each

ingredient amount with only the two measuring cup sizes.
