Explicação passo-a-passo:
Minimo Multiplo Comum
m m c
a) 4/9+5/6= mmc( 9,6) =18
8+15/18=23/18
b) 2+5/8= mmc(1,8)= 8
16+5/8= 21/8
c) 2/15+1/6+2/5 = mmc( 15,6,5)=30
4+5+10/30= 19/30
d) 5/8+7/12= mmc(8,12)=24
15+14/12= 29/12
e) 2/5+3/10= mmc( 5,10)=10
4+3/10=7/10
f) 4/9+1= mmc( 9,1)=9
4+1/9=5/9
g) 1/3+3/4+1/6= mmc( 3,4,6)= 12
4+9+2/12=15/12
