Question

The product of two numbers is $211.2$. If one of these two numbers is $16.5$. Find the other number?

Answer 1

Step: Find the other number
Given:
The product of two numbers = $211.2$
One number = $16.5$

Let $x$ be the other number.
$\therefore x\times 16.5=211.2$
$\Rightarrow x=\frac{211.2}{16.5}$
$\Rightarrow x=\frac{211.2\times 10}{16.5\times 10}=\frac{2112}{165}$
$\therefore$ The other number is $12.8$.
