Question

15 upon 2 + - 11 upon 3 + 6 + - 7/upon

6 + 9 upon 8​

Answer 1

First take LCM of 2 and 3 = 6

15/2 + (-11/3)

15*3/2*3 + ( -11*2/3*2). + + - = -

45/6 - 22/6=. 23/6

23/6 + 6/1 LCM of 6 and 1 is 6

23/6 + 6*6/1*6

23/6 + 36/6= 59/6

59/6 + (-7/6).

59/6 - 7/6. + + - = -

= 52/6

52/6 + 9/8

LCM of 6 and 8 is 24

52*4/6*4 + 9*3/8*3

208/24 + 27/24 =235/24
