Flour:sugar is equal to 3:2.
If we set flour equal to 1.5, we can set up an equation.
Since we are searching for the needed amount of sugar, we will represent it with x.
let x=the needed amount of sugar.
%283%2F2%29=%281.5%2Fx%29
Now, we can cross multiply and solve for x.
3*x=2*1.5
3x=3
x=1
Therefore, for 1.5 cups of flour, you need one cup of sugar.
