Find the product :

0.6 x 1.5 x 0.7

First we multiply 6 by 15 and then by 7

$\begin{matrix} & 1 & 5 \ \times & & 6 \ \hline & \bold{9} & \bold{0} \end{matrix}$

∴ 6 × 15 = 90

$\begin{matrix} & 9 & 0 \ \times & & 7 \ \hline \bold{6} & \bold{3} & \bold{0} \end{matrix}$

∴ 6 × 15 x 7 = 630

Sum of decimal places in given decimals = (1 + 1 + 1) = 3

So, the product contains 3 places of decimal

∴ 0.6 × 1.5 × 0.7 = 0.630 = 0.63
