To change a fraction to a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction, while the denominator is the bottom part of the fraction.
4 ÷ 5 = 0.8
Thus,

Answer:
mode: number that appears most
mode=4 and 7
mean: =3+4+5+6+7+8+9+10+11÷9=7
so mean is 7
Basically, all you have to do is count how many 6 's you have and then write 6^4. Which is 6 to the fourth power.
Let x and (442-x) represent the distance of the trains traveled. X/90 mph=442-x/80 mph
Cross multiply 80×x =90(442-x)
80x=90×442-90x
170x=90×442
X= 90×442/170
X=234, distance traveled by train going 90mph
234mi/90mph = 2.6 hr, time it takes for the two trains tok meet.
Checking your answer:
90×2.6+80×2.6=234mi+208mi = 442mi
