Let's look at an example and you will see. Take 1/2, which is is the same as 5/10, well that is .5. What we did was to take the fraction and rewrite it with a denominator that was 10, 100, 1000, or some power of 10. So 1/5 is 2/10 so it is .2, and 4/5 if 8/10 so it is .8. Some are harder like 1/3 These are repeating decimals whereas the first example was a terminating one. The best way to do these it to divide 3 into 1 by long division and look to see where it repeats.
Sometimes the decimal will repeat only after a certain number of places. Such as .124333333...
You can easily convert to percent by multiplying the decimal you have by 100. .5x100=50% for example.
As a fraction, you can write it as 8/10. As a decimal, you can write it as 0.8.
To write a fraction as a decimal, do the indicated division. 3/4 = 3 divided by 4 = 0.75 To write a decimal as a percent, multiply by 100. 0.75 = 75 percent
Convert the fraction into a decimal. Multiply the decimal by 100.
1.08% is 108/10000 as a fraction, and 0.0108 as a decimal.
9% = 0.09 as a decimal and 9/100 as a fraction.
Fraction: 99/100 Decimal: 0.99
8.1% = 0.081 in decimal = 81/1000 in fraction
210% = 2.1 as a decimal and 21/10 as a fraction
45 percent as a fraction is 45/100 or 9/20. 45 percent as a decimal is 0.45.
A fraction or a percent.
fraction: 4/100 = 1/25 decimal: 0.04
