A car travels 1/6 of the distance between two cities in 3/5 of an hour. At this rate, what fraction of the distance between the
Delvig [45]

<u>Answer:</u>

\frac{5}{18}

<u>Step-by-step explanation:</u>

Distance traveled by a car between two cities = 1/6 distance

Time taken to travel between the two cities = 3/5 hours

Therefore, to find how much of the distance the car can travel in 1 hour, we need to divide the given distance by the given time to get:

(\frac{1}{6}) ÷ (\frac{3}{5})

Change the later fraction to its reciprocal to solve:

\frac{1}{6} × \frac{5}{3} = \frac{5}{18}

Therefore, in one hour, the car can travel 5/18 of the distance.

A researcher receives 106 containers of oxygen. Of those containers, twenty of them have oxygen that is not ionized and the rest
9966 [12]

Answer:

0.1905 = 19.05%

Step-by-step explanation:

We have a total of 106 containers of oxygen, from which:

20 have oxygen not ionized, 86 have oxygen ionized.

If the first one selected is ionized, now we have 20 not ionized and 85 ionized.

So the probability of the second one selected being not ionized is the number of not ionized (20) over the total number of containers (20 + 85):

P = 20 / (20 + 85) = 0.1905 = 19.05%
