Question

Evaluate : $\frac{0.0203\times 2.92}{0.0073\times 14.5\times 0.7}$

• A. $0.2$
• B. $0.3$
• C. $0.6$
• D. $0.8$

Answer 1

Answer: (D)

$0.8$

We will first convert the decimals into fraction in the given fraction and then solve it as follows:

$\frac{0.0203\times 2.92}{0.0073\times 14.5\times 0.7}=\frac{\frac{203}{10000}\times \frac{292}{100}}{\frac{73}{10000}\times \frac{145}{10}\times \frac{7}{10}}$

$=\frac{\frac{203\times 292}{1000000}}{\frac{73\times 145\times 7}{1000000}}=\frac{203\times 292}{73\times 145\times 7}$

$=\frac{29\times 7\times 73\times 4}{73\times 29\times 5\times 7}=\frac{4}{5}=0.8$

Hence, $\frac{0.0203\times 2.92}{0.0073\times 14.5\times 0.7}=0.8$
