Answer 2

The ascending order of the numbers is:

3/5 < 1/2 < 7/9 < 4/5

Given:

The numbers 3/7 , 4/5 ,7/9, 1/2.

To Find:

Ascending order of the numbers 3/7 , 4/5 ,7/9, 1/2.

Solution:

The given numbers are:

3/7 , 4/5 ,7/9, 1/2

To arrange them in ascending order, we need to make their denominators equal.

For that, we have to find the LCM of the numbers present in the denominator of each number.

LCM of 7, 5, 9, 2 is: 7x5x9x2 = 630

Now, the numbers will be:

270/630 , 504/630 , 490/630 , 315/360.

Hence, the ascending order is :

270/630 < 315/630 < 490/360 < 504/360

i.e,

3/5 < 1/2 < 7/9 < 4/5

Hence, the ascending order of the numbers is 3/5 < 1/2 < 7/9 < 4/5.
