Today in math class, we reviewed turning fractions into decimals, and we learned that the least common multiple is the same as the lowest common denominator in a fractions. You turn a fraction into a decimal by dividing the numerator by the denominator. When you're turning a mixed number into a decimal, the decimal will be more than one, and the whole number will be before the decimal point. For example, if the mixed number was 2 and 1/10, the decimal would be 2.10 .
To find the decimal of a fraction, you can put the fraction over 100, then it is easier to find the decimal. For example, if you take 1/5 and put it over 100 as 20/100, it sound like 20 hundreths, which is written as .02 in decimal form.
We learned about two kinds of decimals called terminating and repeating decimals. A repeating decimal is a decimal that never ends, and goes on and on and on and on and on repeating the same 1 or 2 numbers. An example of a terminating decimal is 0.3176 because it doesn't repeat the same numbers on and on forever, and it comes to an end after 4 numbers. On the other hand, the decimal 0.33333 repeats the same number over and over again, which means it is a repeating decimal.
HOW TO TURN A REPEATING DECIMAL INTO A FRACTION!
1. Identify how many digits there are that repeat over and over again.
2. Place the repeating digits in a fraction over the same amount of 9's.
3. Simplify as much as possible.
For Example: the repeating decimal 0.66 would be 6/9, which can be reduced to 2/3
