VIDEO: How to Convert Decimal Numbers to Fractions - That's how it's done

It is required in school and is often necessary. Let them explain how to Decimal numbers converts into fractions and of course also apply it.

What fractions and decimals are

• Fractions and decimals are actually divided natural Countingwhich often come from practice and are therefore easy to explain.
• For example, there are things that are fractions more intelligibly pronounced than in a decimal number. They say a 1/2 (half) full glass rather than 0.5 glass of water or want half a melon and not 0.5 melons.
• Decimal numbers are written with a comma or a point. The whole number is in front and the divided number after the decimal point. 5.7 or 8.25 are e.g. B. such numbers.
• Fractions consist of a numerator above a fraction line and a denominator below it. The fraction line is horizontal, but you can also write a slash.


"How do you convert fractions to decimals?" - Here's how you do it

There are several ways to convert fractions to decimal numbers. So you can possibly ...

• Sometimes decimals and fractions are mixed up too. It looks like this: 3 7/10 or 5 1/4 etc.

How to convert decimals to fractions

1. You convert the decimal numbers into fractions on the basis of powers of ten. This means that you always convert the number to a power of ten first.
2. You first find out how many places are after the decimal point. Then take the corresponding power of ten with as many zeros as the decimal number has decimal places.
3. Now write this power of ten under the fraction line and above it write the complete decimal number without a comma or point.
4. This is how you convert all numbers into fractions. Here are a few examples: 3.5 equals 35/10; 7.25 = 725/100 or 22.275 = 22275/1000.
5. At the end or depending on how the task is, you can shorten the fractions until you can no longer go any further. For example: 2.5 = 25/10 = 5/2 or 0.75 = 75/100 = 15/20 = 3/4.

It can be that easy mathematics be with decimals and fractions.
