Answer:
1/9
Step-by-step explanation:
Let the two no.s be x & y
Given:
x - y = 1/9 ------Eqn 1
x + y = 45 ------Eqn 2
To Find:
HCF (x,y)
Solution:
x = 45 - y ------- from Eqn 2
Substituting {x = 45 - y} in Eqn 1
45 - y - y = 1/9
45 - 2y = 1/9
2y = 45 - 1/9
2y = (405-1)/9 ------Taking LCM
2y = 404/9
y = 404/(9x2)
y = 202/9
Substituting {y = 202/9} in Eqn 1
x - 202/9 = 1/9
x = 1/9 - 202/9
x = 203/9
HCF (x,y):
x = 202/9 = 2 x 101 / 9
y = 203/9 = 7 x 29 / 9
Numbers common in x & y is 1/9
Therefore, HCF (x,y) is 1/9
