Answer 1

a. 3 : 2

b. 2 : 15

c. 3 : 2

Explanation:

Red fish = 3

Yellow fish = 6

White fish = 4

Black fish = 2

Total number of fishes = 15

a) Ratio of the Number of yellow fish to the number of white fish.

Yellow fish : White fish

6 : 4

= 6 /4

= 3/2

= 3 : 2

Ratio of the Number of yellow fish to the number of white fish = 3 : 2

b) Ratio of the Number of black fish to the total number of fish

Black fish : Total fish

2 : 15

= 2 / 15

= 2 : 15

Ratio of the Number of black fish to the total number of fish = 2 : 15

c) Ratio of the Number of red fish to the number of black fish

Red fish : black fish

= 3 : 2

= 3/2

= 3 : 2

Ratio of the Number of red fish to the number of black fish = 3 : 2
