3 : 4 = 12 : 6

2 : 5 = 30 : 75

7 : 9 = 14 : 18

8 : 3 = 64 : 24

Step-by-step explanation:

3 : 4 = 12 : ?

3/4 = 12/?

3 x ? = 12 x 4

3 x ? = 48

? = 48 ÷ 3 = 16

2 : 5 = 30 : ?

2/5 = 30/?

2 x ? = 30 x 5

2 x ? = 150

? = 150 ÷ 2

? = 75

7 : 9 = ? : 18

7/9 = ?/18

7 x 18 = ? x 9

126 = ? x 9

? = 126 ÷ 9

? = 14

8 : 3 = 64 : ?

8/3 = 64/?

8 x ? = 64 x 3

8 x ? = 192

? = 192 ÷ 8

? = 24

The first one is 16 because 4x4=16

The one on the left side on the bottom is 15 because 15x2=30

The right one is 14 because 7x2=14

The last one is 24 because 8x3=24
