hi so the problem is a recipe calls for a total of 3 2/3 cups of flour and sugar. If the recipe calls for 1/4 cup of sugar, how much flour is needed
1. 3 1/12
2. 3 1/4
3. 5/12
4. 3 11/12

The flour-sugar total is 3 2/3 cups, of which 1/4 cup is sugar. So, to find the amount of flour used, we subtract 1/4 cup (sugar) from the total (3 2/3 cups):

11 1

----- - ---- where 11/3 is the improper fraction form of 3 2/3

3 4

The LCD is 12. Rewriting this subtraction using the LCD, we get:

44 3

---- - ----- = 41/12 (cups) = 3 5/12 cups

12 12

3 5/12 cups of flour are needed
