Question 105

A body floats $\frac{2}{9}$ of its volume above the surface. What is the ratio of the body submerged volume to its exposed volume? Rewrite it as a rational number.

Answer 1

Given, volume of body exposed $=\frac{2}{9}$
$\therefore Volumeofbodysubmerged=1-Volumeofbodyexposed$
$=1-\frac{2}{9}=\frac{9-2}{9}=\frac{7}{9}$
$\therefore Requiredratio=\frac{7}{9}:\frac{2}{9}=\frac{7}{9}÷\frac{2}{9}=\frac{7}{9}\times \frac{9}{2}=\frac{7}{2}=7:2$
In rational number $=\frac{7}{2}$
