A container holds 3/4 gallon of oil. Rory is changing the oil on his vehicles and needs 6 containers. How many gallons of oil do

igomit [66]

Answer:

4 1/2 containers needed

Step-by-step explanation:

To do this one, you need to know the 6 = 6/1

So to find the amount of oil needed, you multiply the amount of containers by how much it can hold which, in this case, is 3/4 gallons.

When multiplying fractions, you multiply the top by the top and the bottom by the bottom

so a/b x c/d would be solved by a x c / b x d

therefore

3/4 x 6

= 3 x 6 / 4 x 1

= 18/4

simplified:

9/2 (divide top and bottom by 2)

mixed fraction:

4 1/2

note: top of a fraction is called the numerator and the bottom of a fraction is called a denominator

Hope this helps,

A bag contains 1 blue, 2 green, and 3 red marbles, as shown. What is the probability of drawing a green marble out of the bag wi

Doss [256]

ANSWER

$P(G)= \frac{1}{3}$

EXPLANATION

The number of green marbles in the bag is

$n(G) = 2$

The total number of marbles in the bag is

$n(S)=1+2+3 = 6$

The probability of selecting a green marble from the bag without looking is

$P(G)= \frac{n(G)}{n(S)}$

Substitute the values to get,

$P(G)= \frac{2}{6}$

$P(G)= \frac{1}{3}$
