# CLASS-5REDUCING FRACTIONS TO THEIR LOWEST TERM

Reducing Fractions To Their Lowest Term -

To reduce a given fraction to its lowest term, we divide the numerator and denominator of the given fraction by their common factors.Example

(1) Reduce the following fraction to its lowest form:

64          64 ÷ 2         32

------- = ---------- = -------  [dividing by their common factor 2]

128         128 ÷ 2        64

32         32 ÷ 2          16

=> ------- = ---------- = ------- [dividing by their common factor 2]

64         64 ÷ 2          32

16        16 ÷ 16         1

=> ------ = ---------- = ------ [dividing by their common factor 16]

32        32 ÷ 16         2

Above process is step by step deduction to find lowest term, if we recall number table of 64, then we can find lowest term directly and easily.

64         64 ÷ 64         1

------- = ---------- = ------

128        128 ÷ 64        2

(2) Reduce the following fraction to its lowest form:

66          66 ÷ 2         33

------- = ---------- = -------  [dividing by their common factor 2]

132         132 ÷ 2        66

33         33 ÷ 3          11

=> ------- = ---------- = ------- [dividing by their common factor 3]

66         66 ÷ 3          22

11        11 ÷ 11         1

=> ------ = ---------- = ------ [dividing by their common factor 11]

22        22 ÷ 11         2

Above process is step by step deduction to find lowest term, if we recall number table of 66, then we can find lowest term directly and easily.

66         66 ÷ 66         1

------- = ---------- = ------

132        132 ÷ 66        2
