Answer 1

Lisa will not be able to feed both tanks the same amount of food.

Explanation:

This question is incomplete, here is the complete question :

"Lisa pet shop has 2 fish tank . Tank A contains smaller fish who were fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 gram each per day. If tank B contains 2/3 the number of fish Tank A contains,will Lisa ever feed both tanks the same amount of food."

Let the number of fish in tank A = f

Lisa fed 1 gram of food each per day = f × 1 = f

So,the number of fish in tank B =
`(2)/(3)f`

Lisa fed 2 gram of food each per day =
`(2)/(3)f* 2`

If both the tanks are fed with same amount of food then

`f=(2f)/(3)* 2`

`f=(4f)/(3)`

⇒ 3f = 4f

⇒ 3 = 4

But 3 ≠ 4

Therefore, Lisa will not be able to feed both tanks the same amount of food.
