10*10 = 100 so I would not need to estimate it! The answer is -10 or +10
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.)
To find 10 percent of 160,000, you can multiply 160,000 by 0.10 (which represents 10 percent as a decimal). This calculation results in 16,000. Therefore, 10 percent of 160,000 is 16,000.
You need a second number to ask what 1.9 is a percent of.. Like: what percent is 1.9 of 10?
