Question

I dont ge this either
A radio station broadcasts programs and commericals 20 hours everyday. The ratio of the time spent on commercials to the programming time is 1:4. How much time each day does the station spend broadcasting commercials?

Answer 1

???

Answer 2

et x = amount of time given to commercials
4x = amount of time given to programming

amount of time given to commercials + amount of time given to programming = 20 hours.

x + 4x = 20. Add x-terms.

5x = 20. divide both sides by 5

x = 4.

4 hours are spent on commercials.

Answer 3
