Question

parent results not recorded. continue practising or switch user. which is the most accurate way to estimate 69% of 72? \\(\frac{2}{3} \times 70\\) \\(\frac{7}{10} \times 70\\) \\(\frac{3}{10} \times 70\\) \\(\frac{9}{10} \times 70\\)

Explanation:

Step1: Convert percentage to fraction

$69\%=\frac{69}{100}\approx\frac{7}{10}$ (since $69\approx70$ and $\frac{70}{100}=\frac{7}{10}$)

Step2: Round the number

$72\approx70$

Answer:

$\frac{7}{10}\times70$
