A bag contains 4 oranges, 3 grapefruits, and 8 tangerines. A piece of fruit is chosen from the bag at random. What is the probab
s2008m [1.1K]
What you’ll have to do is find the probability of the oranges and the tangerines. There is a total is 15 fruit. 12 of those are not grapefruit. You’ll then have to find the percentage of 12/15.


12 is divided by 15, then multiplied by 100. 

12 divided by 15 = 0.08

0.08 x 100 = 80

There is an 80% chance that a grapefruit will not be picked.

The product of two rational numbers is 9⁄7 and one of them is 15⁄14. Then the other rational number is​
Rasek [7]

Answer:

The other rational number in the operation given is:

  • <u>6/5</u>

Step-by-step explanation:

To obtain the number in the operation given, we're gonna represent the operation:

  • r * 15/14 = 9/7

Where:

  • r = the other rational number.

Now we are going to solve r to identify its value in numbers:

  • r * 15/14 = 9/7
  • r = \frac{\frac{9}{7} }{\frac{15}{14}} (We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)
  • r = \frac{6}{5}

As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:

  • r * 15/14 = 9/7
  • 6/5 * 15/14 = 9/7
  • 9/7 = 9/7

In this form, we know the result is correct.
