Question

Represent 50 grams as a fraction of a kilogram. (1 kilogram = 1000 grams)

• A. $\frac{1}{20}$
• B. $\frac{1}{40}$
• C. $\frac{1}{50}$
• D. $\frac{1}{10}$

Answer 1

The correct option is A

$\frac{1}{20}$

1 kg = 1000 g,
50 grams as a fraction of 1 kg $=\frac{50}{1000}$
Cancelling the zero, we get
$\frac{5}{100}=\frac{1}{20}$ (reducing to its lowest terms by dividing numerator and denominator by 5)
