5/10=¿?/20
12/3=4/¿?
10/12=5/¿?
50/100=¿?/50

Answer 1

1/3 = 15/x
X= 15/(1/3)
X = 3*15/1
X = 45
1/3 = 15/45

5/10 = x/ 20
5/10 * 20 = x
X= 10
5/10 = 10/20

12/3 = 4/x
X= 4/(12/3)
X = 12/12
X=1
12/3 = 4/1

10/12 = 5/x
X= 5/(10/12)
X = 30/5
X= 6
10/12 = 5/6

50/100= x/50
X= 50/100 *50
X = 25
50/100 = 25/50
