Question

simplifica y resuelve :
a) 10/21 . 5/6 . 14 =
b)20/9 . 12/25 : 8/3 =

Answer 1

primero pasalo a decimales o sea 10 entre 21= 0.4  5/6=0.8 0.8 + 0.4+14=15.2
20 entre 9=2.2 12 entre 25=0.48 8 entre 3=2.6 =1.0

Answer 2

a
(10/21)*(5/6)*14 = (10*5*14) / (21*6*1) = 700/126 = 50/9

b
por partes:
(20/9)*(12/25) = (20*12) / (9*25) = 240/225 = 48/45
por tanto:
(20/9) * (12/25) / (8/3) = (48/45) / (8/3) = (48*3) / (45*8) = 144/360 = 2/5
