a) if 3½ cups make 1½ dozen, how will you find out how to make 1 dozen?
b) how do you get 1½ down to just 1 dozen?
> divide by 1.5
> 1.5 ÷ 1.5 = 1 dozen
c) so now you do it to the other measurement
> 3.5 ÷ 1.5 = 2.33
> 2.33 = 2⅓ cups
d) your answer is:
for every 1 dozen muffins, you need 2⅓ cups of flour
