Find 66 2/3 precent of 87. find 1 precent of 3,620

62 1/2 precent of x is 5 what is x. 300 precent of k is 42 what is k

So 66 2/3 percent of 87 is the same as two thirds of 87 so all you do is 87 divided by 3 and then times by 2 to make 58.

1 percent of 3620 is just 3620 divided by 100 as there are a hundred 1 percents in 3620. This makes 3.62

If 5 is 62 1/2 percent of x then you just do 5 divided by 62 1/2 to find one percent then you times that by 100:
5 divided by 62 1/2 =0.08 (1 percent)
0.08 x 100=8 (100 percent) which is the answer

If 300 percent of k is 42 then all we have to do is divided by 3 as we only want 100 percent which is 14 which is the answer!

Good luck!
