Blank:14 = 1:2
6:blank= 5:35
45:54= blank:24
Blank:63= 42:49

(1) 7

(2) 42

(3)  20

(4) 54

Step-by-step explanation:

We can do 14/2 to get 7 for the answer for number 1. Same would able for the others. Or you can find what the unit rate is for each one and then multiply. Take the second one for example. We see that both 5 and 35 are both divisible by 5. After dividing both by 5 we get the unit rate of 1:7. We can then do (6*1):(6*7) Then we get 6:42. Same concept would apply to the other problems.
