A fraction is a number that is not a whole number. It is written as one number divided another number, e.g. ¾. The top number, 3, is called the numerator and the bottom number, 4, is called the denominator: the denominator can NEVER be zero.
Fractions are read as follows: ⅜ is read as 'three eighths'. The numerator is read as an ordinary counting number, BUT the denominator is read as an ordinal number: third(s), fourth(s), fifth(s) and so on.
Fractions can have a strange effect on some people and they find using decimals preferable. Whatever your preference, it's definitely worth taking some time to play our 11plus Maths quizzes about fractions. This will give you a basic understanding of these funnylooking numbers!

There are five fifths in 1, so there are 5 × 2 = 10 fifths in 2. In general, the number in the denominator tells you how many fractions of that type are needed to make 1. For example, you need three thirds, ^{1}⁄_{3}, to make 1, but you need ten tenths, ^{1}⁄_{10}, to make 1 and so on. REMEMBER this stuff, and you won't get confused with fractions

If you divide the denominator and the numerator by the SAME number, you can reduce the fraction to its simplest form. In this case, you divide the denominator AND the numerator by 2


If you don't know your ordinal numbers, learn them now! For example, 20th = twentieth, 30th = thirtieth, 40th = fortieth and so on

All the other fractions can be reduced to ^{1}⁄_{4} which is smaller than ^{1}⁄_{3} because you are dividing the same numerator, 1 in this case, by a smaller number: 3 in this case


If the denominators are the same, you can add the fractions by simply adding their numerators  it really is as easy as that!

If the denominators are the same, you can subtract the fractions by simply subtracting their numerators  it really is as easy as that! You should get ^{3}⁄_{9} BUT this can be reduced to ^{1}⁄_{3} if you divide the denominator and the numerator by the SAME number, in this case 3


There are seven sevenths in 1. If you have eaten ^{5}⁄_{7}, there can only be ^{2}⁄_{7} left because 5 + 2 = 7: if the denominators are the same, you can add/subtract the fractions by simply adding/subtracting their numerators

^{1}⁄_{2} is the same as ^{3}⁄_{6}: multiply the numerator and denominator by 3


He lost ^{1}⁄_{10} × 10,000 = 1,000 soldiers

The fractions are the same. If you divide the denominator and the numerator in ^{6}⁄_{10} by 2, you will get ^{3}⁄_{5}. The same is true if you multiply the denominator and the numerator in ^{3}⁄_{5} by 2, you will get ^{6}⁄_{10}
