Question

$\frac{3}{100}+\frac{5}{10000}$ is equal to

(a) 0.35
(b) 0.305
(c) 0.0305
(d) 0.3005

Answer 1

(c) 0.0305

3/100 = 0.03 (here, we have the denominator 100, so we mark the decimal such that 3 is in the hundredth place)
5/10000 = 0.0005 (here, we have the denominator 10000, so we mark the decimal such that 5 is in the ten thousandth place)

Therefore, 3/100 + 5/10000 = 0.03 + 0.0005
= 0.0305
