Would it be 270? if you take 90 3 times. due to that there are 3 different durations.
20 because 19 16/33 is the exact answer. Since they ask about how much that can be rounded up to 20
75%
30/40 means its 75% out of 100%
75$ representing the 30 and the 100$ representing the 40
Or for this and any other problem . every percentage is out of a 100
soooo ,
20 | 100 %
10 | 50 %
5 | 25 %
1 | 5 %
SOOO
10 + 5 = 15 50 % + 25 % = 75 % , so know we know 15/20 is 75 percent
but you need 18/20 not 15/20 , so 1 equals 5 % in this problem
1+1+1 = 3 5+5+5 = 15
15 + 3 = 90 75 + 15 = 90 , 18/20 = 90%
I know its probably alot but I wanted to show you all I did , so that it could maybe help you in the future , just gotta plug in different numbers
