Hi there! The most accurate way to estimate 23% of 70 is to write and solve a proportion. You would write it out as x/70 = 23/100, because we’re looking for the number that is 23% of 70. Cross multiply the values to get 1,610 = 100x. Divide each side by 100 to isolate the “x”. When you do, you get x = 16.1. There. 23% of 70 is 16.1.
