The lasagna recipe requires two pounds of ground beef for ever six cups of tomato sauce. How much beef is necessary if you only have one cup of tomato sauce?

Kyle,
look at 2 pounds as 6/3 pounds, (or 6 portions of 1/3 pound of beef.) Then you have an even number to compare with 6 cups. if you only need 1 cup, then you only need 1/3 pound of beef.

Ms. Sue,
One way to solve this is with a proportion. Cross multiply and solve for x.
2/6 = x/1
6x = 2
x = 2/6 = 1/3 pound
