Giải đáp:
a) $148,75 : 3,5 = 42,5$
b) $201,6 \times x = 20,16$
$\to x = 20,16 : 201,6 $
$\to x= 0,1$
Vậy $x=0,1$
c) $x-18,87 = 50,5 : 2,5$
$\to x-18,87 = 20,2$
$\to x=39,07$
Vậy $x=39,07$
a, 148,75 : 3,5 = 42,5
b, 201,6 x X = 20,16
X = 20,16 : 20,1,6
X = 0,1
c, x – 18,87 = 50,5 : 2,5
x – 18,87 = 20,2
x = 20,2 + 18,87
x = 39,07
