Question

The line plot below shows the number of flour packets of different weights. What is the total amount of flour sold by selling $\frac{7}{8}$ pound packets?

• A. $\frac{5}{8}lb$
• B. $\frac{7}{8}lb$
• C. $7lb$
• D. $56lb$

Answer 1

The correct option is C $7lb$

Number of flour packets weighing $\frac{3}{8}lb=4$

Number of flour packets weighing $\frac{5}{8}lb=2$

Number of flour packets weighing $\frac{7}{8}lb=8$

Total amount of $\frac{7}{8}lb$ of flour packet used $=\frac{7}{8}+\frac{7}{8}+\frac{7}{8}+\frac{7}{8}+\frac{7}{8}+\frac{7}{8}+\frac{7}{8}+\frac{7}{8}=\frac{56}{8}=7lb$

The total amount of flour sold by selling $\frac{7}{8}lb$ of flour packets is $\frac{56}{8}lb$ or $7lb$
