To go from percent to decimal, divide by 100. So, 90%/100 is 0.90.
Divide 140 by 100 first to get 1% then multiply it by 90 to get 90% Answer:126
Multiply by 10 and divide by 9
I will tell you how to do it. It's so simple. For example, 36% of 90. So, you first change it to make 36 the numerator and 100 the denominator and multiply it by 90. Like this_ 90 (I couldn't find the right key for fraction and multiplication sign). Then you cancel 36 and 100 and make them smaller like this_36/100 * 90 = 9/25 * 90. I divide it by 4. You can divide it with other numbers. And then watch this...I will divide 90 by 25. 9/25 * 90 = 9/1 * 3.6 = 9 * 3.6 = 32.4 and that is correct. The answer is 32.4!!!
To work out 10%, just divide it by 10. To work out 1%, just divide it by 100. To work out 16%, just A) Work out 10% (divide by 10), then work out 6% (divide by 100, times by 6) and add the two together B) Divide by 100, times the result by 16.This applies for all numbers. To work out 90%, just A) Work out 10% and take it away B) Divide by 100, times the result by 90 C) Work out 10%, times by 9.
