30% = = Steps: 1. Write the percent over a 100 to turn it into a fraction. 2. Re-write the fraction in lowest terms. Your Example: Write 42% as a fraction in lowest terms.
For example: Write 65% as a decimal. (If there is no decimal point in the percent, there is always an invisible decimal point at the end of the last digit. You must move that decimal 2 places to the left. ) 65% = 65. = 0.65 2 places to the left Your Example: Write 4.3% as a decimal.
For example: Write the decimal 0.78 as a percent. 0.78 = 78. = 78% 2 places to the right Your example: Write the decimal 0.875 as a percent.
You can use division to write a fraction as a percent. For example: Write as a percent. Steps: 1. Divide 3 ÷ 5 = 0.6 (You will get a decimal.) 2. Then you must move the decimal point 2 places to the right to rewrite the decimal as a percent. ◦ 0.6 = 0.60 = 60% Move the decimal 2 places to the right Your example: Write the fraction as a percent.
