Multiplicar cruzado:
2/3 = 12/x
2x = 12.3
x = 36/2
x = 18
3/8 = x/40
40.3 = 8x
120 = 8x
x = 120/8
x = 15
4/x = 4/1
4.1 = 4x
x = 4/4
x = 1
x/37 = 403/481
481x = 403.37
481x = 14911
x = 14911/481
x = 31
x/20 = 2/5
5x = 2.20
x = 40/5
x = 8
100/x = 20/50
100.50 = 20x
5000 = 20x
x = 250
2/3 = 12/x
2x = 12.3
x = 36/2
x = 18
3/8 = x/40
40.3 = 8x
120 = 8x
x = 120/8
x = 15
4/x = 4/1
4.1 = 4x
x = 4/4
x = 1
x/37 = 403/481
481x = 403.37
481x = 14911
x = 14911/481
x = 31
x/20 = 2/5
5x = 2.20
x = 40/5
x = 8
100/x = 20/50
100.50 = 20x
5000 = 20x
x = 250
