Question

10) State whether the following ratios are proportional or not:

(i) 20:45 and 4:9
(ii) 9: 27 and 33: 11

Answer 1

Answer:
20:45 is proportional to 4:9
9:27 is not proportional to 33:11

Step-by-step explanation:
To find if two ratios are proportional you can write them as fractions and simplify them.

So 20/45 can be simplified to 4/9

20/5 = 4

45/5 = 9

20/45 = 4/9



9/27 cannot be simplified into 33/11

So it is not proportional
