Question

The value of $(\frac{0.12\times (0.0104-0.002)+0.36\times 0.002)\times 100}{0.12\times 0.12}$ is

Answer 1

$\frac{0.12\times (0.0104-0.002)+0.36\left(0.002\right)}{0.12\times 0.12}=\frac{0.12\times \left(0.0084\right)+0.36\left(0.002\right)}{0.12\times 0.12}$

$=\frac{\frac{12}{100}\times \frac{84}{10000}+\frac{36}{100}\times \frac{2}{1000}}{\frac{12}{100}\times \frac{12}{100}}$ = $\frac{(12\times 84+36\times 20)\times 10000}{12\times 12\times 1000000}$

$=\frac{84+60}{12\times 100}=\frac{7+5}{100}$ = $0.12$
