Question

A body floats 2/9 of its volume above the surface. What is the ratio of the volume of body submerged to its exposed volume? Re-write it as a rational number.

Answer 1

Answer:

7 : 2

Step-by-step explanation:

if 2/9th of the volume of the body floats above the surface, then this is the exposed volume..

then, the submerged volume is 9/9 - 2/9 , as the remaining will be inside the surface.

which is 7/9..

now coming to the ratio.. ratio is just the division of two numbers.

p/q is the way of representing rational numbers... this format could also be used to represent ratio.

we have to find the ratio of submerged volume to it's exposed volume.

submerged is 7/9 , where as exposed is 2/9..

now, we will just have to divide the answers...

So, ratio =

7/9 / 2/9

which is = 7 × 9/2×9

this will be = 7/2

9 will be cancelled out..

This is the ratio...

7:2
