Question

23. Compare the following ratios:
(i) 3 : 10 and 2 : 15 (ii) 5:18 and 7:24​

Answer 1

Answer:

(i) Ans.) 3 : 10 > 2 : 15, (ii) Ans.) 5 : 18 < 7 : 24

Step-by-step explanation:

(i) 3 : 10 and 2 : 15 = 3/10 and 2/15

So, the LCM of  10 and 15 is 30, then

= 9/30 and 4/30

So, 3 : 10 > 2 : 15

(ii) 5 : 18 and 7 : 24 = 5/18 and 7/24

So, the LCM of 18 and 24 is 72, then

= 20/72 and 21/72

So, 5 : 18 < 7 : 24
