Detailed Solution

Given fractions are,

31

and

125

By obtaining the L.C.M. of the denominators and converting the fractions into like fractions, fractions with different denominators can be subtracted.
LCM of 1 and 5 is 5.
Subtracting both the fractions we get,

31 − 125

= 3 × 5 − 12 5 = 15 − 12 5 = 35

Therefore,

3 - \frac{12}{5} = \frac{3}{5}

Therefore, option (3) is correct.
