Question

Mark the correct alternative in each of the following:

0.02 × 0.05 =

(a) 0.1 (b) 0.01 (c) 0.001 (d) 0.0001

Answer 1

In order to find the product, we first multiply 2 by 5.

We have, 2 × 5 = 10

Now, 0.02 has 2 decimal places and 0.05 has 2 decimal places.

The sum of the decimal places is 2 + 2 = 4.

So, the product must contain 4 places of decimals.

∴ 0.02 × 0.05 = 0.0010 = 0.001

Hence, the correct answer is option (c).
