Solve the decimal division: $\frac{0.08}{0.2}$
💡
Step-by-Step Explanation & Concept Rationale
Multiply numerator and denominator by $100$: \[\frac{0.08}{0.2} = \frac{8}{20} = \frac{4}{10} = 0.4\] Thus, the correct option is (B).
Q. 7

Solve the decimal division: $\frac{0.002}{0.8}$
💡
Step-by-Step Explanation & Concept Rationale
Multiply numerator and denominator by $1000$: \[\frac{0.002}{0.8} = \frac{2}{800} = \frac{1}{400} = 0.0025\] Thus, the correct option is (B).
Q. 8
Quantitative Aptitude Test
Difficulty: Medium
(1 Mark)
Solve the decimal division: $\frac{0.8}{0.002}$
💡
Step-by-Step Explanation & Concept Rationale
To divide decimals, multiply both numerator and denominator by $1000$ to eliminate the decimal points: \[\frac{0.8}{0.002} = \frac{0.8 \times 1000}{0.002 \times 1000} = \frac{800}{2} = 400\] Thus, the correct option is (C).
