Question

quanto é 1,5(2/3)+5,3(2/3)+5,8(2/3)+2(2/3)+4(2/3)+2(2/3)+4(2/3)

Answer 1

primeiro....
Simplifique a soma 1,5(2/3)+5,3(2/3)+5,8(2/3)+2(2/3)+4(2/3)+2(2/3)+4(2/3)

2/3,5+152/3,+402/3,+22/3+42/3+22/3+42/3

(2,5)/3+(152,)/3+(402,)/3+(22)/3+(42)/3+(22)/3+(42)/3

(10,)/3, (30,)/3, (80,)/3, 4/3, 8/3, 4/3 e 8/3

10,+30,+80,+4+8+4+8
Reduzir (120,+24)/3 fatorando fora e cancelando os fatores comuns.
a resposta é.... 48, +8
