You'll first have to make both denominators to be less or equal to 12. As you do this, the numerators will change accordingly. From there, you can take any values in between the numerators as your choice. Make sure the resulting fraction has denominator less or equal to 12 and the fraction is in between the 2 fractions in qn.
If you're unsure ill show you.
Ans:
① 3/7
② 4/9
③ 5/11
Denominator must be less than 12
denominator sld be odd number
Try & err
3/7 = 0.43
4/9 = 0.44
5/11 = 0.45
2/5=0.4
1/2=0.5

Why should denominator be odd? Also, Why denominator cannot be 12? Qn says denominator cannot be more than 12. So 12 and below is acceptable?
For this specific question, 12 can be included.
If 12 cannot be counted, the denominator sld be odd. Sorry I did not explain it clearly.

Oh I see. Its ok. Anyways, it's good to look at qns openly. We know how to tackle them in any case. :)
Thx a lot for ur input

Hi there, good afternoon. Mr Pang here. This question tests on concepts of changing denominator and numerator. So 2/5 = 4/10 ; 1/2 = 5/10. So the answer is somewhere 4.5/10 but it is not a fraction. We need something bigger than 4/10. One way is to make numerator bigger, another way is to make denominator smaller. So let's try making denominator smaller. = 4/9. Let us test 4/9. It is bigger than 4/10=2/5, smaller than 5/10=1/2. Bravo!

Hi there. I'm offering an alternative approach to the qn. If you haven’t read my earlier comment. Read it first. Then refer to this solution. Hope it helps. :)
