Fractions | Decimals | Percentages

Fractions are equal pieces of a whole. A decimal is a number that is less than 1. Percentages are the parts in one hundred.

A fraction has two parts to it, a numerator and a denominator. The numerator shows the amount of pieces someone owns, and the denominator shows the amount of pieces the whole is divided into. Fractions are used to represent a piece or segment of a whole. There are also different fractions. They are: improper and mixed number fractions. 

An improper fraction shows that the numerator is more than the denominator. An improper fraction can be converted into a mixed number fraction.

A mixed number fraction is one or more whole and another fraction. To convert an improper fraction into a mixed number fraction, people usually identify the denominator. If the improper fraction is 7/3, people divide 7 by 3. 7 ÷ 3 = 2.3. This means that there are two wholes. 7/3 is equivalent to 2 1/3. 

A decimal is used to represent less than one and can go as high or as low as it can be. The decimal point (.) shows that the number is a decimal. In a decimal, there are tenths, one hundredths and thousandths as the main place values.

A percentage stays within the 100 place value, this means that 100% is the maximum percentage. To find out a percentage, people divide the denominator by 100. If the fraction was 1/4 the number problem would be: 100 ÷ 4 = 25. This means that 1/4 of 24 = 25%.

By understanding how to make fractions, decimals and percentages, it can help people to convert them to each other to make an equation more simple.
