Tex's favorite recipe for barbecue sauce calls for 2 1/3 cups of tomato sauce.

The recipe makes enough barbecue sauce to serve 7 people. How much tomato sauce is needed for 1 serving?

## Check this out

For 7 people->2+1/3 cup of tamato sauce

so for 1->(2+1/3)/7 cup of tamato sauce.

NOTE:its called unitary method and it is really important to understand it.

uhh one serving and serving one are different things.I have have assumed you meant serving one.

That's not much of a party!

This problem demonstrates the general uselessness of the "Mixed" fraction. What is needed, more often than not, is the unfortunately-named "Improper" fraction.

2 1/3 cups = 7/3 cups

$\displaystyle \frac{7/3\;cups}{7} = 1/3\;cup$

Once we had the improper fraction, it was obvious how to proceed dividing by seven.
