प्रश्न

Put the given fraction in ascending order by making denominator equal:

`5/6, 7/8, 11/12  "and" 3/10`

योग

उत्तर

`5/6, 7/8, 11/12  "and" 3/10`

L.C.M. of denominators 6, 8, 12 and 10 = 240

`therefore 5/6 = (5 xx 40)/(6 xx 40) = 200/240`

`7/8 = (7 xx 30)/(8 xx 30) = 210/240`

`11/12 = (11 xx 20)/(12 xx 20) = 220/240`

`3/10 = (3 xx 24)/(10 xx 24) = 72/240`

It is clear from the above that

`72/240 < 200/240 < 210/240 < 220/240`

or `3/10 < 5/6 < 7/8 < 11/12`

Hence, `3/10, 5/6, 7/8 "and" 11/12` are in ascending order.
