Arrange the following rational numbers in ascending order:.
3/5 -7/10 7/18 -2/3
​

Answer 1

Given: 3/5 , -7/10 , 7/18 , -2/3

LCM of denominators= 90

3/5 x 18/18 = 54/90

-7/10 x 9/9 = -63/90

7/18 x 5/5 = 35/90

-2/3 x 30/30 = -60/90 -:To make the denominators same,hence comparing numerators

Now,comparing 54/90 , -63/90 , 35/90 , -60/90

-63/90 < -60/90 < 35/90 < 54/90

OR

-7/10 < -2/3 < 7/18 < 3/5.
