Olá ,bom dia ☺

Resolução:

a) (25/56) x (14/15)=350/840 : 70/70=5/12
b) (9/16) x (12/28)=108/448 :  4/4 = 27/112
c)(1/6) x ( 3/4) x ( 15/7) = 45/168 : 3/3 = 15/56

Bons estudos :)

Answer 2

Olá bem é simples:

a) (25/26) . (14/15) =
350/840 ÷ 70/70 
= 5/12

b) (9/16) . (12/28) =
108/448 ÷ 4/4 
= 27/112

c) (1/6) . (3/4) . (15/7) =
45/168 ÷ 3/3
= 15/56

Bom dia
