Question

Sam covered 12 km of his 100 km road trip. What part of the distance has he covered?

• A. 0.88
• B. 1.2
• C. 0.012
• D. 0.12

Answer 1

The correct option is D 0.12

Given that Sam covered 12 km of his 100 km road trip, he has covered $(\frac{12}{100}{)}^{th}$ part of his 100 km road trip.

$\because$ In the fraction, the denominator is a power of 10 and there are two zeroes after one in it, the decimal point in numerator would be shifted by two units to the left.
$\Rightarrow \frac{12}{100}=0.12$
$\therefore$ Sam has covered $0.12$ part of his road trip.
