Question

a recipe call for 1 1/2 cup of flour for every 2/3 cups of sugar.

for 2 1/3 cups of flour how much sugar is needed

Answer 1

You can set this up as a standard proportion problem Sydny R.

Solve for the variable by setting the two ratios as equal, cross multiply, and then divide.

flower / sugar = flower / sugar

1 1/2 / 2/3 = 2 1/3 / X

3/2X = 14/9

X = 14/9 / 3/2

X = 14/9 x 2/3

X = 28/27

X = 1 1/27
