1/30

as the denominators are different you cannot directly subtract.

To solve this , first find out LCM of denominators that is 30

30/5 =6

so multiply numerator and denominator of first fraction with 6

1* 6/5*6 =6/30

30/6=5

so multiply numerator and denominator of first fraction with 5

1*5/6*5=5/30

now subtract (6-5)/30=1/30
