minha ajuda trabalho

Answer 1

$b)60. \dfrac{5}{70} =6. \frac{5}{7} = \dfrac{30}{7}~~~c) d\frac{2}{3}.10. \dfrac{3}{2} =10~~~~d) \dfrac{6}{5} .5. \frac{2}{4} = \dfrac{12}{4} =3~~ \\ \\ e) \dfrac{11}{4}. \dfrac{3}{20} = \dfrac{33}{80}$

Answer 2

60 x 5/70 = 300/70 = 30/7

2/3 x 10 x 3/2 = 10 x 6/6 = 10

6/5 x 5 x 2/4 = 30/5 x 2/4 = 6 x 2/4 = 12/4 = 3

11/4 x 3/20 = 33/80
