Question

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?

Answer 1

We have:

Song 1 = 3 1/10 minutes

Song 2 = 4 2/3 minutes

Minutes of memory of two songs:

`3(1)/(10)+4(2)/(3)=(31)/(10)+(14)/(3)=(3*31+10*14)/(30)=(93+140)/(30)=(233)/(30)=7(23)/(30)`

Answer:

`7(23)/(30)\text{ minutes}`
