Apopulation of 10,000 bees doubles every month. determine the population of bees eight months ago.

Step-by-step explanation:

y x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = z

z/2/2/2/2/2/2/2/2

1/2 1/4 1/8 1/16 1/32 1/64 1/128 1/256

8 months ago = today/256

answer: just subtact the units and then add the non negative : happy to

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.
