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

Answer 1

To find percentages of numbers, convert the percent to a decimal and then multiply. To find the unknown quantity in an equation involving percentages, divide the given number by the percent expressed as a decimal.

Step-by-step explanation:

To find 66 2/3 percent of 87, first convert the percent to a decimal by dividing it by 100: 66 2/3 ÷ 100 = 0.6667. Then multiply the decimal by 87: 0.6667 x 87 = 58.33. So, 66 2/3 percent of 87 is approximately 58.33.

To find 1 percent of 3,620, divide 3,620 by 100: 3,620 ÷ 100 = 36.2. So, 1 percent of 3,620 is 36.2.

To find x in the equation 62 1/2 percent of x is 5, first convert the percent to a decimal: 62 1/2 ÷ 100 = 0.625. Then divide 5 by the decimal: 5 ÷ 0.625 = 8. So, x is 8.

To find k in the equation 300 percent of k is 42, first divide 42 by 300: 42 ÷ 300 = 0.14. So, k is 0.14.

Answer 2

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!
