A body floats 2/9 of its volume above the surface. What is the ratio of the body submerged volume to its exposed volume? Re-write it as a rational number.
Solution:
It is given that
Volume of body exposed = 2/9
We know that
Volume of body submerged = 1 - Volume of body exposed
Substituting the values
= 1 - 2/9
= (9 - 2)/ 9
= 7/9
Here
Required ratio = 7/9 : 2/9
It can be written as
= 7/9 ÷ 2/9
= 7/9 × 9/2
= 7/2
= 7: 2
Therefore, the ratio of the body submerged volume to its exposed volume is 7/9 : 2/9 and the rational number is 7/2.
