Dao has \(2 \frac{3}{8}\) pounds of hamburger meat. He is making \(\frac{1}{4}\)-pound hamburgers.
Does Dao have enough meat to make 10 hamburgers? Explain.
Answer (2)
To find if there is enough, here is the equation 4 1 × 1 10 You multiple across 1×10=10 and 4×1=4= 4 10 Then you divide the numerator(top) by the denominator(bottom) 10÷4= 2 4 2 ⇒ 2 2 1 To see if they equal, you multiply just the fraction by four 2 1 × 4 4 = 8 4 Thus the answer is 2 8 4 which is larger than 2 8 3 Dao has enough meat to make 10 hamburgers because 2 8 4 > 2 8 3
Dao needs 2 2 1 pounds of hamburger meat to make 10 hamburgers, which is equivalent to 8 20 pounds. Dao has 2 8 3 pounds, or 8 19 pounds. Since 8 19 < 8 20 , Dao does not have enough meat to make 10 hamburgers.
