1) Calcule o m. m.c ( no mínimo múltiplo comum) do seguintes números: a)6 e 10=
b)4 e 8=
c)12 e 20=
d)18 e 24=

C. because 6÷3=2 so 3 is half of six so 3/6

None of those are technically correct. 9.7 x 104 is actually 1,008.8, but if that answer was a choice, it would be that one. if you meant 9.7 times maybe a thousand or more or divided by 10 or more, than the answer choices would be correct, but other than that, they actually arent.
