Evaluate:
`(2xx1/4) - ((-18)/7 xx (-7)/15)`
उत्तर
`= ((2xx1)/(1xx4)) - (((-18)xx(-7))/(7xx15))`
`= ((1xx1)/(1xx2)) - (((-18)xx(-1))/(1xx15))`
`= 1/2 - 18/15`
| 2 | 2, 15 |
| 3 | 1, 15 |
| 5 | 1, 5 |
| 1, 1 |
LCM of 2 and 15 is 2 x 3 x 5 = 30
`= (1xx15)/(2xx15) - (18xx2)/(15xx2)`
LCM of 2 and 15 = 30
`= (15-36)/30 = (-21)/30 = (-7)/10`
