You were on the right track.
(17/4)*(11/4)*(3/1)
first multiply the numerators
17*11*3 = 561
561 / ?
next multiply the denominators
4*4*1 = 16
561 / 16 = 35.0625 = 35 1/16
I think c!!!!!!!!!!!!!!!!!!!!
0.28
2 divided by 7 is 0.28
All you have to do is divide the numerator by the demoninator in order to get your decimal.
The answer is 4 hours
p -<span> the programming time
</span>c - time spent on commercials
<span>A radio station broadcasts programs and commercials 20 hours everyday:
p + c = 20
</span><span>The ratio of the time spent on commercials to the programming time is 1:4.
c : p = 1 : 4
p = c * 4 : 1
p = 4c
p + c = 20
p = 4c
_____
4c + c = 20
5c = 20
c = 20 : 5
c = 4h</span>
