Answer:
6.125 minutes per song
Step-by-step explanation:
Unit rates are based on a single unit of something. Like price per 1 gallon of gas; price for 1 pound of bananas; miles driven per 1 gallon of gas, etc. What we are looking for in minutes per song.
Use a proportion to solve this with minutes on top and number of songs on the bottom. We know that 49 minutes = 8 songs, and we want to know how many minutes (x) per 1 song:

Cross multiply to get
8x = 49 so
x = 6.125 minutes per song
Is there any way you can take a picture of the problem? I cannot interpret the way you asked your problem.
Answer:
26
Step-by-step explanation:
22*0.2=4.4
22+4.4=26.4
when you round you will get 26
(you should probably ask your teacher which way to round.)
12%
40% = 0.4
30 = 0.3
0.3 x 0.4 = 0.12
0.12 = 12%
