    Answer:

    your answer is 5.55

    Step-by-step explanation:

    3/2+4/5+12/5+6/7

    lcm of 2 , 5 , 5 and 7 is 70

    3*35/2*35 + 4*14/5*14 + 12*14/5*14 + 6*10/7*10

    105/70 + 56/70 + 168/70 +60/70

    389/70

    OR

    5.55

    Answer:

    5.843

    Step-by-step explanation:

    3/2 + 4/5

    taking LCM of 2 and 5 as 10

    =(3 x 5)/(2 x 5) + (4 x 2)/( 5 x 2)

    =15/10 +8/10

    =(15+8)/10

    =23/10

    =2.3

    12/5 + 6/7​

    taking LCM of 5 and 7 as 35

    =(12 x 7)/(5 x 7) + (6 x 5)/(7 x 5)

    =84/35 + 30/35

    =(84+30)/35

    =124/35

    =3.5428

    =3.543

    therefore the sum of 3/2 + 4/5 & 12/5 + 6/7​

    =2.3 + 3.543

    =5.843

    HOPE THIS HELPS YOU!!!!
