Fraction is said to be in the simplest (or lowest) form if its numerator and denominator have no common factor except 1.

To simplify a fraction, we can divide the top and bottom of the given number by the highest common factor (HCF) of the numerator and denominator.

__Let’s consider fraction 15/75.__Find HCF of 15 and 75.

5

15, 75

3

3, 15

1, 5

HCF of 15 and 75 = 5 x 3 = 15

Now, divide the top and bottom of the given number by 15.

Therefore,

1/5 fraction is in lowest term.

Example 1: Write the simplest form of 16/72.

Solution: HCF of 16 and 72.

2

16, 72

2

8, 36

2

4, 18

2, 9

HCF of 16 and 72 = 2 x 2 x 2 = 8

Now, divide the top and bottom of the given number by 8.

Therefore,

2/9 fraction is in lowest term.

Example 2: Write the simplest form of 17/51.

Solution: HCF of 17 and 51.

17

17, 51

1, 3

HCF of 17 and 51 = 17

Now, divide the top and bottom of the given number by 17.

Therefore,

1/3 fraction is in lowest term.

Example 3: Write the simplest form of 42/28.

Solution: HCF of 42 and 28.

2

42, 28

7

21, 14

3, 2

HCF of 42 and 28 = 2 x 7 = 14

Now, divide the top and bottom of the given number by 14.

Therefore,

3/2 fraction is in lowest term.

Example 4: Reduce the fraction 48/60 to simplest form.

Solution: HCF of 48 and 60.

2

48, 60

2

24, 30

3

12, 15

4, 5

HCF of 48 and 60 = 2 x 2 x 3 = 12

Now, divide the top and bottom of the given number by 12.

Therefore,

4/5 fraction is in lowest term.

Example 5: Is 49/64 in its simplest form?

Solution: HCF of 49 and 64.

1

49, 64

49, 64

HCF of 49 and 64 = 1

Fraction is in the simplest (or lowest) form because numerator and denominator of the given number have no common factor except 1.
