Question

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.
