Question

If, $317\times 45=14265$, then $3.17\times 4.5=?$

Answer 1

Given $317\times 45=14265$
Consider $3.17\times 4.5=3.17\times \frac{100}{100}\times 4.5\times \frac{10}{10}$
[Multiplying $\frac{100}{100}$ and $\frac{10}{10}$ for $3.17$ and $4.5$ respectively]
$=\frac{317\times 45}{100\times 10}$
$=\frac{14265}{1000}$ [Since, given ]
$=14.265$
