Answer 2

Answer:

Arrange the following in descending order:

1,. 3,. 7

-. -. -

5. 7. 10

We need to arrange these in descending order.

To find which number is greater or smaller,

We make their denominators equal.

Common denominator = LCM of 5, 7, 10

= 2x5x7

= 10 x 7

= 70

So,

1 14 14 -X 5 14 70 = 5

3 7 3 7 10 10 30 70

7 10 7 10 7 7 49 70

Therefore,

In descending order

49 30 14

-. -. -

70' 70' 70

i.e.7 3 1

10 '7 '5
