The recipe ratio was given. The recipe uses "two parts" of flour, and the number of parts available is 7 parts of flour. How much bigger is the recipe that is needed? 7%2F2. Wanted is to use ALL of the available flour.

Milk?
3%287%2F2%29=21%2F2=10%261%2F2 "parts" or cups

Sugar?
1%287%2F2%29=7%2F2=3%261%2F2 "parts" or cups
