$\frac{7}{20}$ $7/20$

For the addition and subtraction of fractions, there must be a common denominator

the common denominator for these fractions is 20

Multiply the fractions (numerator and denominator) to achive a common denominator

So,

= $\frac{3 \cdot 4}{5 \cdot 4} - \frac{1 \cdot 5}{4 \cdot 5}$ $(3*4)/(5*4)-(1*5)/(4*5)$

= $\frac{12}{20} - \frac{5}{20}$ $12/20 - 5/20$

Subtract the numerators,

= $\frac{7}{20}$ $7/20$
