Your answer

$\frac{3}{4} + \frac{8}{5} \\ \\ firstly \: we \: have \: to \: take \: the \: lcm \: of \: the \: denominators \: \\ \\ the \: LCM \: of\: the \: \: denominators \: 4 \: and \: 5 \: is \: 20 \: \\ \\ now \: \\ we \: have \: to \: divide \: the \: denominator \: with \: lcm \: and \: multiply \: the \: numerator \: with \: the \: quotient\\ \\ = \frac{15 + 32}{20} \\ \\ = \frac{47}{20}$
