Answer:
12 pm noon
Step-by-step explanation:
The least common multiple of the two times is 240 minutes, or 4 hours. The buses will meet at the station again at noon.
__
60 = 20×3
80 = 20×4
The least common multiple is 20×3×4 = 240 minutes. There are 60 minutes in an hour, so this is 240/60 = 4 hours. 4 hours after 8 am is 12 pm, noon.
The complete control is 1267
<span>Example: 56.25%/100 = .5625, Next, count the number of digits to the right of the decimal point, say that number is n, and multiply and divide the decimal by 10^n. For your example n = 4 so multiply and divide the decimal by 10^4, which is 10000, giving 5625/10000 which is the fraction sought. This last operation converts the decimal fraction to a whole number needed for the numerator of the fraction. </span>

Answer:
3/50
Step-by-step explanation:
There are 5 + 4 + 2 + 6 + 3 = 20 marbles in the bag
P(draw a black) = 6/20 = 3/10
If the black marble is replaced, then there are 20 marbles in the bag again.
P(draw a blue) = 4/20 = 1/5
P(draw a black and blue with replacement) = (3/10)(1/5) = 3/50
