10*10 = 100 so I would not need to estimate it! The answer is -10 or +10
39 % of 25 is: 4 x (10% of 25) minus (1% of 25).
No need for a calculator. 10% of 100 is equal to (0.1)(100) = 10. If you wanted to use a calculator, just multiply 0.1 times 100.
Multiply the number by the percent in decimal form. Example: 10 percent of 200 would be 200 x .10 = 20. (10 per cent of 200 is 20.)
I am not sure I understand the question but 31% of 78 is: 0,31 * 78 = 24 (24,18 rounded to two significant figures)
Estimation: 80% of 10 = 8 Actual: 79% of 13 = 10.27
