Question

your dog's water bowl is 3/4 full. After taking a drink, the water bowl is 1/3 full. what fraction of the bowl did your dog drink?

Answer 1

the answer is 5/12 because you simplify it to the least denominator and that get you 9/12 - 4/12
9-4
--------- = 5/12
12

Answer 2

Let amount of water that , my dog's water bowl can hold=x cubic unit

Level of water upto which my dog's water bowl is filled

`=(3x)/(4) \text{Cubic unit}`

Let amount of water drank by my Dog in a drink=y cubic unit

Writing the statement in terms of equation

`(3x)/(4)-y=(x)/(3)\\\\y=(3x)/(4)-(x)/(3)\\\\y=(9x-4x)/(4 * 3)\\\\y=(5x)/(12)`

Fraction of the bowl did my dog drank is equal to
`(5)/(12)`
