Kristy downloads two songs to her MP3 player. The songs are 3 1/10 minutes and 4 2/3 minutes long. About how many minutes of memory will these two songs use altogether?

Respuesta :

We have:

Song 1 = 3 1/10 minutes

Song 2 = 4 2/3 minutes

Minutes of memory of two songs:

[tex]3\frac{1}{10}+4\frac{2}{3}=\frac{31}{10}+\frac{14}{3}=\frac{3\times31+10\times14}{30}=\frac{93+140}{30}=\frac{233}{30}=7\frac{23}{30}[/tex]

Answer:

[tex]7\frac{23}{30}\text{ minutes}[/tex]
