Question

arrange in ascending order
2:3 , 7 : 12 , 13: 19​

Answer 1

Answer:

7:12, 2:3, 13:19

Step-by-step explanation:

We need to arrange in the ascending order

The ratios are as follows:-

2:3 , 7 : 12 , 13: 19​

Now the LCM of denominators

= LCM (3, 12, 19)

= 228

So,

2:3 = (2*76):(3*76) = 152:288

7:12 = (7*19):(12*19) = 133:228

13:19 = (13*12):(19*12) = 156:228

Clearly,

133 < 152 < 156

=> 133/288 < 152/288 < 156/288

=> (7:12) < (2:3) < (13:19)
