Question

quero resolver essas questões e não to conseguindo, me ajudem3/2+7/3=9/3+1/4=7/3+3/4-2/4=6/7-1/3+4/3=

Answer 1

3/2+7/3  = mmc 2,3=6
9/6+14/6=23/6
9/3+1/4=  mmc 3,4=12
36/12+3/12=39/12(simplificando por 3)=13/4
7/3+3/4-2/4= mmc3,4,4=12
28/12+9/12-6/12=
37/12-6/12=31/12
6/7-1/3+4/3= mmc 7,3,3=21
18/21-7/21+28/21=
11/21+28/21=39/21(simplificando por 3)=13/7
