Question

Mark (✓) against the correct answer
1.1 × .1 × .01 = ?

(a) .11
(b) .011
(c) .0011
(d) none of these

Answer 1

(c) .0011
First, we will find the product 11 $\times$ 1 $\times$ 1.
i.e., 11 $\times$ 1 $\times$ 1 = 11 $\times$ 1 = 11
Sum of decimal places in the given decimals = (1 + 1 + 2) = 4

∴ 1.1 $\times$ 0.1 $\times$ 0.01 = 0.0011 [4 places of decimal]
