Evaluate: `7/26 + 2 + (-11)/13`
Advertisements
उत्तर
`7/26 + 2 + (-11)/13`
`=> 7/26 + 2/1 + (-11)/13`
| 2 | 26, 13 |
| 13 | 13, 13 |
| 1, 1 |
L.C.M. of 26 and 13 = 2 × 13 = 26
`=> (7 xx 1)/(26 xx 1) + (2 xx 26)/(1 xx 26) - (11 xx 2)/(13 xx 2)`
(∵ L.C.M. of 26 and 13 = 26)
`=> (7 + 52 - 22)/26`
`= (59 - 22)/26 = 37/26`
