There are two ways to convert a fraction into a decimal. The first way is to do it by using place values. Look at the decimal, if it is a regular decimal all you have to do is to use place values. If the decimal is 0.33. Use place values. Ones, then tens, then hundreds. The answer is 33/100, because you keep the numbers in the decimal and just put in the place value as the denominator. I the decimal is 3.42, then go for the place value again. Ones, tens, hundreds. The number is 42/100 and add the 3 and therefore the number is 3 42/100. However, you are not done, simplify 3 42/100, which equals 3 21/50.
Another way is to multiply or find the least common denominator. If the decimal was .11, then make it into a fraction by putting a one under it. Next, you get .11/1, then multiply it with 100. You should get 11/100. Since you don't need to simplify the answer is still 11/100. If it were to be a mix number like 1 11/100 when you convert it to a fraction, keep the one or whole number and you should end up with 1 11/100. I prefer using the least common multiple, to convert the decimal into a fraction because it is easier not to remember all the place values. Also, multiplying by a hundred is simple and cannot be hard.
