18. 12 am is midnight.
There is no such time as 1200 am: there is 12 noon and 12 midnight. The question cannot, therefore, be answered.
600% of 1200 = 600% * 1200 = 6 * 1200 = 7200
1200-600=600
1200/2=600
1200 ÷ 20 = 60
1200
There are 1200/60 = exactly 20 hours
1200/60=20
5,300
600 hours = 0.82 months.
24 hours a day, so 1200 / 24 = 50 days.
Multiply 600 by 2/3. 600 x 2/3, 600 x 2 = 1200, 1200/3 = 400.
