A bread recipe calls for 3/4 cups of flour and 1/5 cup of sugar. based on the recipe, what is the amount of sugar that should be used with 1 cup of flour?
A. 3/20 CUP
B. 4/15 CUP
C. 3 3/4 CUPS
D. 6 2/3 CUPS
to get one cup we can multiply by the reciprocal. (the oppisite of the current fraction) 3/4*4/3 = 1. so then we need to raise the sugar by the same variable 1/5 * 4/3. cross multiplication gives us 1*4=4 3*5=15 4/15
