When finding a fraction of an amount, the key rule to remember is to divide the amount by the denominator and multiply your answer by the numerator. If asked to increase or decrease an amount by a fraction make sure you add or subtract from the original amount at the end of the question!

To find the unit fraction of a number, you need to divide the number by the denominator. To find five-sixths, we need to multiply our answer by the numerator which is 5.

The six kinds of fractions are, proper fractions, improper fractions, mixed fractions, like fractions, unlike fractions and equivalent fractions.

Decimal and Fraction Conversion

Fraction | Equivalent Fractions | Decimal |
---|---|---|

1/3 | 2/6 | .333 |

2/3 | 4/6 | .666 |

1/4 | 2/8 | .25 |

3/4 | 6/8 | .75 |

Example: 3/4 means: We have 3 parts. Each part is a quarter (1/4) of a whole.

3/4 isn’t a whole number. You can write it as a decimal: 0.75.

0.375

The denominator of a fraction tells you the relative size of the pieces. Therefore, the reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Answer: LCM of 3, 4 and 5 is 60.

The numbers are (3 x 40), (4 x 40) and (5 x 40). Hence, required H.C.F. = 40….Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is:

A) 870 | B) 900 |
---|---|

C) 810 | D) 780 |

Say we have listed the first few multiples of 4 and 5: the common multiples are those that are found in both lists: The multiples of 4 are: 4,8,… The multiples of 5 are: 5,… Notice that 20 and 40 appear in both lists?

step 3There is no common factors between the integers, therefore the GCF (3, 4 & 5) is equal to 1.

We found the factors 10, 15, 20 . The biggest common factor number is the GCF number. So the greatest common factor 10, 15, 20 is 5.

Greatest common factor (GCF) of 3 and 20 is 1.
