Answers
Given : Rational numbers
7/15 , 11/20 , 2/5 , 12/25
To Find : difference between greatest and the smallest rational number
3/20
3/10
10/3
20/3
Solution:
7/15 , 11/20 , 2/5 , 12/25
15 = 3 x 5
20 = 2 x 2 x 5
5 = 5
25 = 5 x 5
LCM = 2 x 2 x 3 x 5 x 5 = 300
7/15 = 140/300
11/20 = 165/300
2/5 = 120/300
12/25 = 144/400
Largest 165/300
Smallest 120/300
Difference = 165/300 - 120/300
= 45/300
= 9 /60
= 3/20
