50% of 20 is 10. Therefore, 20 +10 = 30
50 percent
30
the increase is 50%
percent increase = 50% % increase =|original value - new value|/original value * 100% = |20 - 30|/20 * 100% = 10/20 * 100% = 0.50* 100% = 50%
Finding 30 percent of a number is the same as multiplying the number by 0.3. In this instance, 0.3 x 50 = 15. Therefore, 30 percent of 50 is equal to 15.
20/0.5 = 40 x 0.75 = 30 Seventy-five percent of the number is therefore 30.
20 to 30 is a 50% increase.
70
That would be 1/10th of 50. 50 * (1/10) = 5 If you wanted 20%, you could find it the same way: 50 * (1/20) = 10 30%: 50 * (1/30) = 15 And so on... You could also use decimals: 10%: 50 * 0.1 = 5 20%: 50 * 0.2 = 10 30% 50 * 0.3 = 15 And so on...
