28 cell phone cases in all. 
6 of the 28 cases are fabric. 

6/28 simplified to 3/14 

So the answer to your question would be 3/14

Hope this helps! :)

Let me help assist you.
This question is asking for, in simplified form, the fraction that the customer will select the fabric case. We will start by making the fraction.
First, let's add the total number of cases.
10 + 12 + 6 = 28.
There is 28 cases in all. Let's subtract the number of fabric cases.
28 - 6 = 22.
With this information, we can make the fraction, which is 6/28.
The question asks for simplest form, however. Now that we have the fraction, we can proceed to this step.
We have to find the GCD of the numerator and denominator, which is 2.
Now, we have to divide both 6 and 28 by the GCD (2).
6 ÷ 2 = 3
28 ÷ 2 = 14
The simplest form of 6/28 is 3/14.

Hope this answers your question correctly.

A tennis supply store pays a wholersale $90 for a tennis racquet and sells it for $114. What is the markup rate?
damaskus [11]

First, what you want to do is subtract the price you sell it for by how much you got it for.

In this case, your equation would look like this: 114 - 90 = 24

You added $24 to the price that you bought. The amount added to the price would be $24

Then you would divide the amount added to the price by the amount it costed you to buy. It would end up as a decimal:

24 ÷ 90 = 0.266 (infinite 6's)

Then with the decimal you got, you would multiply it by 100 to get the markup rate percentage.

0.266 × 100 = 26.66

The markup rate would be 26.66% (26.7 if you round).

malfutka [58]

The theoretical probaility of drawing an ace from a shuffled deck of playing cards is 1/13.

According to the given question.

A card is drawn from a shuffled standard deck.

Since, the total number of cards in a shuffled standard deck = 52

And, the total number of aces in a shuffled standard deck = 4

As, we know that "the theoretical probability of an event is the number of desired outcomes divided by all possible outcomes".

Therefore, the theoretical probabability of drawing an ace from a shuffled deck of playing cards

= 4/52

= 1/13

Hence, the theoretical probaility of drawing an ace from a shuffled deck of playing cards is 1/13.

Step-by-step explanation:

Water is the universal solvent" with a grain of salt (pun intended). Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Water's solvent properties affect all life on Earth, so water is universally important to all of us.
