In order to write a fraction as a decimal or a percent, you can write the fraction as an equivalent fraction with a denominator of 10 (or any other power of 10 such as 100 or 1,000), which can be then converted to a decimal and then a percent. Therefore, 60 percent is same as 60 over 100 or 60/100. The greatest common factor of 645 and 1,000 is 5, so you can divide the numerator and denominator by 5 to get. The place value of the last digit (the 5) is thousandths, so the denominator is 1,000. To write 0.645 as a fraction, use 645 as the numerator. To write 0.645 as a percent, move the decimal place two places to the right: 64.5%. Remember that when you convert a decimal to a percent you have to move the decimal point two places to the right. In the same way, rewriting a decimal as a percent (or as a fraction) requires few steps. to change simplified fraction form 2/3 to decimal form and percent form. People often skip over the intermediary fraction step and just convert a percent to a decimal by moving the decimal point two places to the left. Converting between fractions and decimals: Converting from decimals to. For example, 81% can be written as, and dividing 81 by 100 results in 0.81. Converting a percent to fraction form is easy: simply write the percentage as the numerator of the fraction and use one hundred as the denominator. Any percentage x can be represented as the fraction, and any fraction can be written as a decimal by moving the decimal point in x two places to the left. You can use fractions to understand why this is the case. In a particularly sunny month, Solaire's solar panels generated 110 110\ 1 1 0 110, percent as much. Notice that in the previous example, rewriting a percent as a decimal takes just a shift of the decimal point. Notice in the diagram below that 25% of a grid is also of the grid, as you found in the example. You can also just move the decimal point in the whole number 25 two places to the left to get 0.25. Simplify the fraction by dividing the numerator and denominator by the common factor 25. You write this as a fraction, using 100 as the denominator. Since % means “out of 100,” 25% means 25 out of 100. Write 25% as a simplified fraction and as a decimal.
