Question

Change the following groups of fractions to like fractions:

`1/3,2/5,3/4,1/6`

Answer 1

`1/3,2/5,3/4,1/6`

L.C.M. of denominators 3, 5, 4, 6 = 60

2	3,	5,	4,	6
3	3,	5,	2,	3
	1,	5,	2,	1

= 2 × 3 × 1 × 5 × 2 × 1 = 60

Now, `1/3=(1xx20)/(3xx20)=20/60`;

`2/5=(2xx12)/(5xx12)=24/60;3/4=(3xx15)/(4xx15)=45/60`

`1/6=(1xx10)/(6xx10)=10/60`

`1/3,2/5,3/4and1/6=20/60,24/60,45/60,10/60`
