It is a rational number which is less than 1. If the absolute value of the numerator is less than the absolute value of the denominator then the fraction is a proper fraction.

If it's one of those ordinary ones you write ([numerator]/[denominator])

Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.

Either 8/10,or 4/5,or 16/20.These are the basic ones. And then there's fractions like 32/40,64/80,128/160.Those are the ones where you just double thenumerator and the denominator You can also do things like 80/100,800/1000.Those are the ones where you multiply the numerator and denominator by 10,over and over again.Hope I answered it!!!!!!!!

4.5 as a decimal is 4.5. 4.5 is four ones and 1/2 of 1. So, as a mixed fraction, it would look like: 4 1/2. As an improper fraction, you would multiply the denominator by the number to the left of it, add the numerator to the product, and put the sum over the original denominator. 4x2=8. 8+1= 9. 9/2 is 4.5 as an improper fraction.

Great question! :)The numerator and denominator are relatively prime.If you factor the numerator into the product of its primes, and factor the denominator into its product of primes, there are no primes to cancel:4 / 5 = 2 * 2 / 5since the only primes in the numerator are 2, and the only ones in the denominator are 5, they cannot divide into each other for further simplication.For a contrast, consider 4 / 6.Here you can rewrite 4 / 6 as (2 * 2) / (2 * 3).In this case, a 2 in the numerator cancels with a 2 in the denominator, reducing the fraction to 2/3. One way of visualizing the cancellation is below:(2 * 2) / (2 * 3) = 2 / 3.

So, the number you are given is 5 8/10 To calculate the number of tenths, you multiply the number of ones by the denominator and add it to the numerator Thus, 5 X 10 = 50 50 + 8 = 58 There are 58 tenths

When working with decimals you have to remember that it goes (ones).(tenths)(hundredths)(thousandths)(ten-thousandths) and so on. the digit "6" is in the thousandths place and therefor is six thousandths or (6/1000) which can be simplified to (3/500) by dividing the numerator and the denominator by two.

91 since the ones digit is 8 less than 9 and the two digits, 9+1 = 10, a two-digit number.

4.5 as a decimal is 4.5. 4.5 is four ones and 1/2 of 1. So, as a mixed fraction, it would look like: 4 1/2. As an improper fraction, you would multiply the denominator by the number to the left of it, add the numerator to the product, and put the sum over the original denominator. 4x2=8. 8+1= 9. 9/2 is 4.5 as an improper fraction.

Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.

It is 58.
