    Answer:

    there are

    16, 8, 12 and 4 different animals

    Step-by-step 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
