Answer:
Lisa will not be able to feed both tanks the same amount of food.
Step-by-step 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 = [tex]\frac{2}{3}f[/tex]
Lisa fed 2 gram of food each per day = [tex]\frac{2}{3}f\times 2[/tex]
If both the tanks are fed with same amount of food then
[tex]f=\frac{2f}{3}\times 2[/tex]
[tex]f=\frac{4f}{3}[/tex]
⇒ 3f = 4f
⇒ 3 = 4
But 3 ≠ 4
Therefore, Lisa will not be able to feed both tanks the same amount of food.
