Answer 1

Answer:

-251/72

Step-by-step explanation:

Given that

= 11/12+(-17/4)+(-4/9)+(-15/8)+13/6

= 11/12-17/4-4/9-15/8+13/6                               (Opening the brackets)

= 11/12-17/4-4/9-45+52/24                              ( L.C.M. of 8 and 6 is 24)

= 11/12-17/4-4/9+7/24

= 11/12-17/4-32+21/72                                      ( L.C.M. of 9 and 24 is 72)

= 11/12-17/4-11/72

= 66-306-11/72                                                ( L.C.M. of 12, 4 and 72 is 72)

= -251/72                                                         (ANS.)

USE B.O.D.M.A.S. TO ADD FRACTIONS FIRST RATHER THAN SUBTRACTING THEM.
