2 and 1/2 = 2 and 5/10 = 2.5
Any kind of fraction becomes decimal notation if you divide the denominator into the numerator. Any decimal notation becomes a percent if you multiply it by 100.
Well, honey, 16.5 is already a fraction. It's what we call a decimal fraction. But if you want to turn it into a common fraction, just move that decimal point two places to the right to get 165/10. And don't worry, math won't bite... usually.
Find a common denominator.
If its not an improper fraction then you cant....
They are both ways of representing parts of whole numbers.
To convert a decimal to a fraction, we can write the decimal as a fraction with the decimal as the numerator and a power of 10 as the denominator. In this case, 3.9 can be written as 39/10. To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 1. Therefore, 3.9 as an improper fraction is 39/10.
To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal as the numerator and a power of 10 as the denominator. In this case, 0.929 can be written as 929/1000. To simplify this fraction, you can divide both the numerator and denominator by their greatest common factor, which in this case is 1. Therefore, 0.929 as a fraction is 929/1000.
common sense
First you convert the decimal into a mixed-number/fraction. Then you have to find the common denominator and compare.
A fraction has a numerator set above its denominator If the numerator is less than the denominator then it is a common fraction as for example 3/4 which as a decimal is 0.75 If the numerator is greater than the denominator then it is an improper fraction as for example 5/4 which as a decimal is 1.25
To turn a decimal like 9.05 into an improper fraction, you first need to convert the decimal into a fraction. Since 9.05 has two decimal places, you can write it as 905/100. To simplify this fraction, you can divide the numerator and denominator by their greatest common divisor, which is 5 in this case. Therefore, 9.05 as an improper fraction is 181/20.
You can get the decimal equivalent of a fraction, by dividing the numerator by the denominator. For example, to convert 1/3 to a decimal, you divide 1 by 3. This is equal to 0.333333... If you need this as a percentage, you multiply by 100; in this case, 33.3333...%
