Help me with this pls

Answer:
3 - 1/2 cup of sugar per cup of flour
Step-by-step explanation:
First what we need to do is convert the fraction so both denominators are equal. Multiply the numerator and denominator of 1/2 by 2.
This would get you 2/4 cups of flour.
Because 1/2 (to answer three) equals to 2/4, you would have to multiply the denominator by 2 again to get one cup of flour.
Your answer would be 1/2 cups of sugar per cup of flour.
