Find the **MEAN**, **MEDIAN**, and **MODE**:

//**78, 45, 45, 78, 60, 75**//

1) Did you remeber to arrange it into numerical order? **45, 45, 60, 75, 78, 78** I prefer doing the numbers in **ASCENDING** order. Now will do it step by step starting with the **MEAN:**
 * ANSWER**:
 * 1) 45 + 45 + 60 + 75 + 78 + 78= 381 << **SUM OF ALL DATA**
 * 2) 6 **PIECES OF DATA**
 * 3) 381**/6****=**63.5 << **average**. also known as the... **MEAN**,

MEAN**=63.5 ILLUSTRATIONS**:

Now we will figure out the **MEDIAN:**
 * 1) Match the pairs.
 * 2) 2 **MIDDLE NUMBERS**
 * 3) 60+75= 135
 * 4) 135/2=67.5 <<**middle number**, also known as the... **MEDIAN**


 * MEDIAN=67.5

And finally the...**MODE**. Don't forget to indicate it!
 * 1) Find the numbers showing up the most.

MODE**=45 and 78**

//Find the square root of// //**78**.//


 * ANSWER:

WHOLE NUMBER**: I will show you a **BUBBLESHARE** presentation so you can see how to solve the whole number. media type="custom" key="27271" DENOMINATOR** media type="custom" key="27278"

Now all you have to do is combine them together... **8 14/17**. Remember that it is just an estimate.



Is taking 15% off an item and then taking an additional 10% the same as taking off 25% all together? Why or why not?


 * ANSWER**: Taking **15% off** an item, and then taking **another 10%**, **isn't** the same as taking **25%** off all together. When you take off 15% on item that costs, **$100** for example, **$85** would remain. **100-15=85**. We don't have to do equivalent fractions or anything like that here because fractions are **out of 100** and that's how much are example price is. Now we have to take off 10%. To do that, we need to **divide the reduced price by 10**. So, **85/10=8.5**. 8.5 subtracted from 85 is __**76.5**__.

 * Ilustration:

Now, when you subtact **25%** off **100,** all you need to do is **take away** 25**. 100-25=75.** We will now **COMPARE** the two answers.

//Use// //**EQUIVALENT FRACTIONS** to solve this question. Jacob has a record of winning **2** boxing matches for every **5** he loses. If he had **49** boxing matches during the last year, how many did he win?//


 * ANSWER**: I will be using another **BUBBLESHARE** like I did for all the other questions to present my work. This is one that I made before and I used for another math assignment. So if you're wondering why the colour scheme for this Bubbleshare isn't green, then know you know.
