Answer:
(a) Angel fish = 48
(b) Goldfish = 36
Step-by-step explanation:
The ratio of clown fish to angel fish at a pet store = 5:4
The ratio of angel fish to goldfish = 4:3
Using these ratios, we conclude that
Clown fish : Angel fish : Goldfish = 5:4:3
Let the number of Clown fish, Angel fish and Goldfish are 5x, 4x and 3x respectively.
There are 60 clown fish at the pet store.
Divide both sides by 5.
The value of x is 12.
Angel fish :
Goldfish :
Therefore, the number of angel fish and goldfish are 48 and 36 respectively.

Answer:
The number is 12
Step-by-step explanation:
[] First, let's turn all these words into something mathematical. N will equal "my number"
-><u> If you add 12 to my number</u> and then multiply the result by 3, you will get 64 more than two-thirds of my number.
-> n + 12 <u>and then multiply the result by 3</u>, you will get 64 more than two-thirds of my number.
-> 3(n + 12), you will get 64 more than <u>two-thirds of my number</u>.
-> 3(n + 12) = <u>64 more than</u>
-> 3(n + 12) = 64 +
[] Phew, okay. Now it is something we can solve and less scary;
[Given]
3(n + 12) = 64 +
[Distribute]
3n + 36 = 64 +
[Multiply both sides by 3]
9n + 108 = 192 + 2n
[Subtract 108 and 2n from both sides]
7n = 84
[Divide both sides by 4]
n = 12
