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

To find if there is enough, here is the equation
$\frac{1}{4}$×$\frac{10}{1}$
You multiple across
1×10=10 and 4×1=4=$\frac{10}{4}$
Then you divide the numerator(top) by the denominator(bottom)
10÷4=$2 \frac{2}{4}$⇒$2\frac{1}{2}$
To see if they equal, you multiply just the fraction by four
$\frac{1}{2}$×$\frac{4}{4}$=$\frac{4}{8}$
Thus the answer is $2 \frac{4}{8}$ which is larger than $2 \frac{3}{8}$
Dao has enough meat to make 10 hamburgers because $2\frac{4}{8}$>$2 \frac{3}{8}$
