21 is 30 % of the number which is found to be seventy.
The next number in the sequence 3-15-6-30-21 is -207.
To find the percent that a number, x, is out of another number, y, divide x by y and multiply by 100. So (21/30)*100 = 70, which means that 21 is 70% of 30.
30% is 0.30 so, 0.30 x 70 = 2100 move the decimal to the left 2 times and get 21 and 21 is your answer!
Let's represent the number as "x". The given equation can be written as 2x - 12 = 30. Adding 12 to both sides, we get 2x = 42. Finally, dividing both sides by 2, we find that x = 21. So, the number is 21.

21 is 30% of 70
21 is 70% of 30.
The next number in the sequence 3-15-6-30-21 is -207.
To find the percent that a number, x, is out of another number, y, divide x by y and multiply by 100. So (21/30)*100 = 70, which means that 21 is 70% of 30.
75/30 = 21/2
210
3 is the hcf
30% is 0.30 so, 0.30 x 70 = 2100 move the decimal to the left 2 times and get 21 and 21 is your answer!
To find 21 percent of a number, multiply the number by 0.21. In this instance, 0.21 x 70 = 14.7. Therefore, 21 percent of 70 is equal to 14.7.
30. Here's how:21 times 10 = 210210 divided by 7 = 30Check:30 times 0.7 = 21
I would say 21, because it is not an even number like the rest are.
30 hundredths equal 3 tenths or 0.3
