उत्तर
`(-5)/9 + (-7)/12 + 11/18`
| 2 | 9, 12, 18 |
| 2 | 9, 6, 9 |
| 3 | 9, 3, 9 |
| 3 | 3, 1, 3 |
| 1, 1, 1 |
L.C.M. of 9,12 and 18 = 2 × 2 × 3 × 3 = 36
`=> (-5 xx 4)/(9 xx 4) + (7 xx 3)/(12 xx 3) + (11 xx 2)/(18 xx 2)`
(∵ L.C.M. of 9, 12 and 18 = 36)
`=> (- 20 - 21 + 22)/36`
`= (-41 + 22)/36 = (- 19)/36`

Find three rational numbers equivalent to `-5/9`
Arrange the given rational numbers in ascending order:
`7/10 , (-11)/-30 "and" 5/-15`
Multiply: `1 1/8 "and" 10 2/3`
Multiply: ` 35 "and" (-18)/25`
Multiply: `3 3/5 "and" -10`
Evaluate: `(7/8 xx 8/7) + ((-5)/9) xx (6/-25)`
Evaluate: `(11/-9 xx 21/44) + ((-5)/9) xx (63/-100)`
Divide: `15/28 "by" 3/4`
Divide: `(- 22)/9 "by" 11/18`
The product of two rational numbers is 24. If one of them is `- 36/11`, find the other.
