Question

Arrange the following fractions in ascending order (a) 5/7 , 3/8, 9/14, 30/10​

Answer 1

Answer:

5/7,3/8,9/14 and 20/21

Here the LCM of 7,8,14 and 21 is 168

5/7=(5×24)/(7×24)=120/168

3/8=(3×21)/(8×21)=63/168

9/14=(9×12)/(14×12)=108/168

20/21=(20×8)/(21×8)=160/168

So we get

63/168<108/168<120/168<160/168

It can be written as

3/8<9/14<5/7<20/21

1. Therefore, 3/8,9/14,5/7 and 20/21 are in ascending order.
