**Use benchmarks to estimate each sum.**

Example

Question 13.

9\(\frac{6}{7}\) + 7\(\frac{5}{12}\)

Answer:

17\(\frac{1}{2}\)

Explanation:

\(\frac{6}{7}\) is near to the benchmark 1

\(\frac{5}{12}\) is near to the bench mark \(\frac{1}{2}\)

9 + 1 = 10

10 + 7 \(\frac{1}{2}\)

17\(\frac{1}{2}\)

Question 14.

4\(\frac{7}{12}\) + 10\(\frac{1}{9}\)

Answer:

14 \(\frac{1}{2}\)

Explanation:

\(\frac{7}{12}\) is near to the benchmark \(\frac{1}{2}\)

\(\frac{1}{12}\) is near to the bench mark 0

10 + 0 = 10

4\(\frac{1}{2}\) + 10

= 14 \(\frac{1}{2}\)
