Mr. Burkett is making cookies. The recipe calls for 3/5 cups of sugar for every 2 1/2 cups of butter. How many cups of sugar should he use for 1 cup of butter?
Please enter your answer in as a fraction, using the / key to separate the numerator from the denominator.
2 1/2 = 2 + 1 / 2 = 4 / 2 + 1 / 2 = 5 / 2
For 1 cup of butter he use
( 3 / 5 ) / 2 1/2 = ( 3 / 5 ) / ( 5 / 2 ) =
3 • 2 / 5 • 5 = 6 / 25
cups of sugar
OR
3 / 5 = 0.6 , 2 1/2 = 2.5
0.6 / 2.5 = 0.6 • 10 / 2.5 • 10 = 6 / 25
