Question

Mark the correct alternative in each of the following:

The value of 2.2 × 0.2 × 0.001 is

(a) 4.2 (b) 0.00044 (c) 4.4 (d) None of these

Answer 1

In order to find the product, we first multiply 22 by 2.

We have, 22 × 2 = 44

Now, 2.2 has 1 decimal place, 0.2 has 1 decimal place and 0.001 has 3 decimal places.

The sum of the decimal places is 1 + 1 + 3 = 5.

So, the product must contain 5 places of decimals.

∴ 2.2 × 0.2 × 0.001 = 0.00044

Thus, the value of 2.2 × 0.2 × 0.001 is 0.00044.

Hence, the correct answer is option (b).
