It is a terminating decimal and so it is a decimal representation of a fraction.
If you start with a fraction p/q and are told that x/y is an equivalent fraction, then the simplest check is to cross-multiply: p*y must be equal to q*x.
You can check by cross-multiplication. For example, to check whether 1/2 is equivalent to 3/6, multiply 1 x 6 = 6, and 2 x 3 = 6 (the numerator of each fraction with the denominator of the other fraction). Since in this case the results are equal, the two fractions are equivalent.
to add decimals: -line up the decimal points -then starting at the farthest place to the right, add the decimal in each place -if the sum of the digits in a place are greater than nine,regroup the number to the place to its left. -check the sum by writing each decimal as an equivalent fraction and then adding these numbers or mixed numbers.
1. Convert the decimal number .36 to a fraction by multiplying it by an equivalent fraction as follows: .36 * 100/100 = 36/100 2. Simplify the fraction to lowest terms: a. find a number that will evenly divide into both the numerator & the denominator (in this case, that number is 4) b. divide the numerator by 4 (i.e. 36/4=9) and divide the denominator by 4 (i.e. 100/4=25). c. Take the results of the above calculations & write your new fraction as: 9/25. d. repeat step 2 until you are unable to find a number that will evenly divide into both the numerator & the denominator. In this case, only 1 iteration is needed because 9/25 is the simplest fraction that is equivalent to .36. 3. Check your fraction to ensure it is equal to the original decimal value by dividing 9 by 25 (e.g. 9/25 = .36 <-- this is equal to the original decimal value, so this check proves you did your factoring & simplification properly).
It is a terminating decimal and so it is a decimal representation of a fraction.
If you are trying to compare a given decimal to a given fraction, you can divide the fraction out and compare the result to the given decimal. For example, 1/2 = 1 divided by 2. = 0.5 3/4 = 3 divided by 4. = 0.75

0.47. check it out for yourself. this in a fraction is 47/100. get a calculator and divide 47 by 100.

16% = 16/100You can divide a percentage by 100 to get it's decimal/fraction value.16/100 = 8/50 = 4/25Simplify the fractionThe answer is 4/25If you check on a calculator, you should get .16 which is 16% as a decimal.
Check your work by doing the division. 0.94 = 47/50 47 divided by 50 = 0.94
If its decimal representation is either terminating or a repeating number then it is rational. Otherwise it is irrational.
The easiest way is cross multiplication.A fraction a/b = c/d if and only if ad = bc
