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 = 
Lisa fed 2 gram of food each per day = 
If both the tanks are fed with same amount of food then


⇒ 3f = 4f
⇒ 3 = 4
But 3 ≠ 4
Therefore, Lisa will not be able to feed both tanks the same amount of food.
219,544.50 is the correct answer because add it up
Shaded part means the yellow part
- The two sets are S and Y.
- The centre intersection part is A

- All the areas occupied by both sets is AUB .
Rest part :-

Let X be large frames and Y be small frames.
X+Y=23
15X+5Y=195 or 3X+Y=39
Thus 2x=16
so X=8
so Y=15
