Question

simple
-3/10 + 3/-20 +7/15 +9/-10 + (-13/20) + 13/15 ( using suitable properties ) ​

Answer 1

Answer:

Step-by-step explanation:

First take the LCM of denominators the LCM will be = 60

  =           -18+(-18)+28+54+(-39)

        ______________________

                         60

=        -18+28+54-39

      ________________

                60

=      10+54-39

    ___________

           60

=      64-39

    ________

         60

=       25

        ___

        60

= If you will reduce it then we get = 5/12

        AND IN MIXED FRACTION WE GET =           2

                                                                           2   ___

                                                                                  5

Answer 2

Step-by-step explanation:

lcm=60

-3x6/10x6 +3x3/-20x3 +7x4/15x4 +9x6/10x6 +13x3/20x3 +13x4/15x4

-18/60 +9/60 +28/60 +56/60 +39/68 +52/60

-18+9+28+56+39+52/60

-27+84+91/60

57+91/60

148/60

37/15(ans)
