At the zoo, there are 75 exotic birds of the 75 birds, 32% of them are male. How many of the
75 birds are male?
A. 8
B. 16
C. 24
D. 32

C. 24.

Step-by-step explanation:

Make 32% into a decimal so you can put it into an equation. 32% as a decimal is .32. 75 x .32 is 24. 24 birds are male.

it is x=-4

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
