estimate. which sign makes the statement true?\n$\frac{9}{10} \times 16\frac{1}{5}$? $\frac{2}{9} \times 17\frac{1}{2}$
Answer
Explanation:
Step1: Estimate the left - hand side
Round $\frac{9}{10}$ to 1 and $16\frac{1}{5}$ to 16. Then $\frac{9}{10}\times16\frac{1}{5}\approx1\times16 = 16$.
Step2: Estimate the right - hand side
Round $\frac{2}{9}$ to $\frac{1}{4}$ and $17\frac{1}{2}$ to 18. Then $\frac{2}{9}\times17\frac{1}{2}\approx\frac{1}{4}\times18 = 4.5$.
