Question

Estimate the following products.

c) $3,895\times 270\times 15$

Answer 1

Now,Round off the numbers to their highest places.

In $3,895$, the highest place is thousands and so it is rounded off to $4,000$.

In $270$, the highest place is hundreds and so it is rounded off to $300$

In $15$, the highest place is tens and so it is rounded off to $20$

So, $$\begin{gathered} 4,000\times 300\times 20 \\ =2,40,00,000 \end{gathered}$$

Actual product is $1,57,74,750$.
