Let's see what to do buddy...

Step-by-step explanation:

$first \: \: \: \frac{1}{4} \: \: \:of \:a \: song \: needs \: \frac{1}{8} \: \: minute. \\ \\ second \: \: \: \frac{1}{4} \: \: of \: a \: song \: needs \: \frac{1}{8} \: minute \: too. \\ \\ also \: the \: third \: and \: fourth \: \: \: \frac{1}{4} \: \: \: of \: a \: song \: need \: \frac{1}{8} \: minute \: . \\ \\ so \: we \: have \: completly \: have \: 4 \times \frac{1}{8} \\ \\ which \: means \: edi \: needs \: 4 \times \frac{1}{8} = \frac{4}{8} = \frac{1}{2} \: minute \: to \: play \: all \: the \: song.$
