recipe for six dozen cookies calls for 2 ½ cups of flour. How many cups of flour are needed for 10 dozen cookies?

Sagot :

2 ¹/₂ cups = 2.5 cups

Let x be the cups of flour needed for 10 dozens:

6 dozens  =  10 dozens
  2.5                 x

(6) (x) = (2.5) (10)

6x = 25

6x/6 = 25/6

x = 25/6   or  4 ¹/₆ cups

4 ¹/₆ cups are needed for the recipe of 10 dozen cookies.
