The water in a swimming pool increased from 4.5 to 6 feet. what is the percent in the water level rounded to the nearest tenth of a percent

(6) / (4.5) = 4 / 3  =  1.333...

The level increased by 33-1/3 % .

The old level was  75%  of the new level.

The amount of water in the pool also had to
increase  33-1/3 % .  If you didn't have that
much water to put in the pool, you couldn't
change the surface level from  4.5ft  to  6ft .

Hope this ; )
