1) 14 : 30

2) 24.5 : 52.5

3) 3.5 : 7.5

4) 1 : 2.14

5) 0.47 : 1

6) 5.6 : 12

7) 9.33 : 20

Step-by-step explanation:

To get the answer for any gaps on the left e.g. 14 : __

divide the number that you have (14) by the number you were given (7).

And multiply your answer (2) by the number on the side you want to get (15), whatever you get from that (30) is you final answer.

To get the answer for any gaps on the right e.g. __ : 12

divide the number that you have (12) by the number you were given (15).

12÷15

And multiply your answer (0.8) by the number on the side you want to get (7)

0.8×7

whatever you get from that (30) is you final answer.
