Question

Q1 Find the fraction equivalent of 4/28 with denominator 7.
Q2 Reduce 15/25
to its simplest form.

Answer 1

Solution:

Reduce a Fraction










Therefore H.C.F. of 21 and 56 is 7.

We now divide the numerator and denominator of the given fraction by 7.

²¹/₅₆ = 21÷756÷7
21
÷
7
56
÷
7
= ³/₈.


2. Reduce ⁴⁸/₆₄ to its lowest form.

Solution:

First we find the HCF of 48 and 64 by factorization method.

The factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

The factors of 64: 1, 2, 4, 8, 16, 32, and 64.

The common factors of 48 and 64 are: 1, 2, 4, 8, 12 and 16.

Therefore, HCF of 48 and 64 is 16.

Now ⁴⁸/₆₄ = 48÷1664÷16
48
÷
16
64
÷
16


[Dividing numerator and denominator by the HCF of 48 and 64 i.e., 16]

⇒ ⁴⁸/₆₄ = ³/₄




3. Reduce ⁴⁴/₇₂ to its lowest form.

Solution:

First we find the HCF of 44 and 72 by factorization method.

The factors of 44: 1, 2, 4, 11, 22 and 44.

The factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36.

The common factors of 44 and 72 are: 1, 2 and 4.

Therefore, HCF of 44 and 72 is 4.

Now ⁴⁴/₇₂ = 44÷472÷4
44
÷
4
72
÷
4

[Dividing numerator and denominator by the HCF of 44 and 72 i.e., 4]

⇒ 44/72 = 11/18
