A family consumes 5/8 of a one gallon container of milk every three days worth of milk every three days. How much milk does the
GenaCL600 [577]

Essentially what you're given is the following

[total gallons for the specified time] = [gallons]*[days]\\

The easiest way to approach this problem is to use the given information to find the amount of milk the family consumes over the course of a day.

\frac{5}{8} = g*3\\\\\frac{5}{8} = 3g\\\\\frac{5}{8 * 3} = g\\\\g = \frac{5}{24}

So now that we know that the family drinks \frac{5}{24} gallons of milk each day, we can multiply by the desired amount of days to discover how much milk the family drinks over that period of time.

g = \frac{5}{24} * days\\g = \frac{5}{24} * 4\\g = \frac{20}{24}\\g = \frac{5}{6}

So from this, we now know that the family drinks \frac{5}{6} gallons of milk over the course of 4 days.

HELP. ME!!!
Natali5045456 [20]

Answer:

3.37 times

Step-by-step explanation:

Probability of hitting and odd number= 3/5

Probability of hitting and odd number=2/5

Probability of hitting and odd number three times= (3/5)^3

Probability of hitting and odd number three times=(2/5)^3

Now

(3/5)^3 / (2/5)^3 = 3.37

Hence Probability of hitting an odd number three times is 3.37 times more than the probability of hitting an even number three times !
