`(8/5 xx (-3)/2) + ((-3)/10 xx 9/16)`
Advertisements
Solution
`= ((8xx(-3))/(5xx2)) + (((-3)xx9)/(10xx16))`
`= (4xx(-3)/(5xx1)) + ((-3xx9)/(10xx16))`
`= -12/5 + ((-27)/160)`
| 2 | 160, 5 |
| 2 | 80, 5 |
| 2 | 40, 5 |
| 2 | 20, 5 |
| 2 | 10, 5 |
| 5 | 5, 5 |
| 1 |
LCM of 5 and 160 = 160
`= ((-12)xx32)/(5xx32) + ((-27)xx1)/(160xx1)`
`= (-384-27)/160 = (-411)/160`
