    1. a) 25 : x= 16 : 10
    25 : x = 1,6
    x  = 25: 1,6
    x  = 15,625
    1. b) 210 : x= 14,92 – 6,52
    210 : x = 8,4
    x   = 210 : 8,4
    x    = 25

  1. 25 : x = 16 : 10
    x = 25 : 1,6
    x = 15,625
    $\text{Vậy x = 15,625}$
    210 : x = 14,92 – 6,52
    x = 210 : 8,4
    x = 25
    $\text{Vậy x = 25}$
