Question

Dao has 2 3/8 pounds of hamburger meat. He is making 1/4 -pound hamburgers. Does dao have enough meat to make 10 hamburgers? Explain

Answer 1

2 and 3/8 turns into 19/8=2/1=2

1/4 * 2/1= 1/2= 0.5

Dao does not have enough hamburger meat.

Answer 2

$Dao \: has \: 2 \frac{3}{8} \: pounds\: of \: meat= \frac{19}{8} pounds\\ meat \: used\: to \: make \: 1 \: hamburger = \frac{1}{4} \: pounds \\ meat \: used \: tomake \: 10 \: hamburgers = \frac{1}{4} \times 10 \\ = \: \: \: \: \: \: \: \: \: \: \frac{10}{4} = \frac{10}{4} \times \frac{2}{2} = \frac{20}{8} \\ \\ now \: \frac{19}{8} < \frac{20}{8} \\ doesnot \: have \: enough \: meat \: to \: make \: 10 \: hamburgers$
