Answer 1

there are

16, 8, 12 and 4 different animals

Explanation:

Step-by-step explanation:

Step one:

given data

Number of Animals = 40

The given ratio is = 4:2:3:1

The total ratio is = 4+2+3+1= 810

Step two;

Applying the part to all method

The first animal

4/10=x/40

cross multiply

10x= 40*4

divide both sides by 10

x= 160/10

x= 16

for second we have

2/10=x/40

cross multiply

10x= 40*2

divide both sides by 10

x= 80/10

x= 8

for the third we have

3/10=x/40

cross multiply

10x= 40*3

divide both sides by 10

x= 120/10

x= 12

for the fourth we have

1/10=x/40

cross multiply

10x= 40*1

divide both sides by 10

x= 40/10

x= 4
