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.
The next number in the sequence 3-15-6-30-21 is -207.
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.
30
21 is 30% of 70
21 is 70% of 30.
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.
The next number in the sequence 3-15-6-30-21 is -207.
75/30 = 21/2
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!

210
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.
14 and 21, and 21 and 28 are the number pairs between 15 and 30 that have 7 as their greatest common factor.
