Which set of ratios below is equivalent to 4:5

there's no picture but what you should do to get an answer is divide the new ratio by the corresponding number of the given ratio

the given ratio here is 4:5

an incorrect example:

pretend you have a new ratio of 18:21

divide 18 by 4 and 21 by 5

you get 4.5 and 4.2

this means that the ratios are not equivalent

what should happen is that after dividing you should get the same number

a good example is a new ratio of 20:25

if you divide 20 by 4 you get 5 and if you divide 25 by 5 you get 5

so the number are the same, and the ratios are equivalent

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
