Question

bob purchases 3 1/3 tons of gravel and 4 2/3 tons of sand. how many tons of material does bob buy?

Explanation:

Step1: Convert mixed numbers to improper fractions

\(3\frac{1}{3}=\frac{3\times3 + 1}{3}=\frac{10}{3}\)
\(4\frac{2}{3}=\frac{4\times3 + 2}{3}=\frac{14}{3}\)

Step2: Add the two improper fractions

\(\frac{10}{3}+\frac{14}{3}=\frac{10 + 14}{3}=\frac{24}{3}\)

Step3: Simplify the result

\(\frac{24}{3}=8\)

Answer:

8
