Question

Simplifique as Frações
4/12=
30/70=
75/150=
24/72=
18/81=
15/90=

Answer 1

$a) \frac{4}{12} \\ \\ mdc(4,12)= 4 \\ \\ \frac{4/4}{12/4}= \frac{1}{3}$

Answer 2

4/12 : 4 = 1/3
30/70 : 10 = 3/7
75/150 : 25 = 3/6 : 3 = 1/2
24/72 : 2 = 12/36 : 6 = 2/6 : 2 = 1/3
18/81 : 9 = 2/9
15/90 : 5 = 3/18 : 3 = 1/6
