Question

arrange the followings in descending order. (a) 1/2,1/3,2/5,3/7​

Answer 1

Answer:

1/2,3/7,2/5,1/3

Step-by-step explanation:

take LCM for all the denominators and then arrange them in order to arrange them properly

Answer 2

1/2,1/3,2/5,3/7

.....take LCM by multiplying denominators as they are all prime.....which is 210.

Therefore,1/2=105/210

1/3=70/210

2/5=42/210

3/7=90/210

So descending order is 1/2,3/7,1/3,2/5
