can foodA=foodB 
a=4/3 A 
Lisa wouldnt ever feed both tanks the same amount of food.

Answer 2

Answer:

No, lisa will not be able to feed both the tanks same amount of food.

Step-by-step explanation:

 No, lisa will never be able to feed both tanks the same amount of food.

Let tank A contains x number of fish then according to the information given

Tank B contains 2/3x number of fish

Lisa feds 1 gm of food in tank A that means  $x\cdot1=x$

Lisa feds 2 gm of food in tank B that means $\frac{2x}{3}\cdot2$

we have to tell whether lisa will ever feed both tanks the same amount it will be possible if

$x=\frac{2x}{3}\cdot2$

$\Rightarrow 3x=4x$   which is not possible

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