There are 32 black fish in the tank
Step-by-step explanation:
Nanci has a large fish tank that contains fish
- The ratio of orange fish to black fish is 5 : 8
- Nanci has a total of 20 orange fish
We need to find how many black fish in the tank
∵ The ratio between the orange fish to the black fish is 5 : 8
∵ She has 20 orange fish
By using the ratio method
→ orange : black
→ 5 : 8
→ 20 : x
By using cross multiplication
∵ 5 × x = 20 × 8
∴ 5 x = 160
- Divide both sides by 5
∴ x = 32
∵ x represents the number of the black fish
∴ The number of the black fish is 32
There are 32 black fish in the tank
