Solution

The correct option is C
$0.0225$

The given expression 0.15 can be written as $\frac{15}{100}$

Squaring this we get

${(\frac{15}{100})}^{2} = \frac{15 \times 15}{100 \times 100} = \frac{225}{10, 000} = 0.0225$

\frac{0.24 \times 0.35}{0.02 \times 0.14 \times 0.15}

\frac{0.85 \times 0.85 \times 0.85 + 0.15 \times 015 \times 0.15}{0.85 \times 0.85 - 0.85 \times 0.15 + 0.15 \times 0.15}

Prove that $\frac{0.85 \times 0.85 \times 0.85 + 0.15 \times 0.15 \times 0.15}{0.85 \times 0.85 - 0.85 \times 0.15 + 0.15 \times 0.15} = 1.$
