Okay. Here is the first question: Determine the result of 10 + –4. How far away on the number line will this result be from 10 and in what direction? P.S there are eight questions.

What do you think it is..?

The numbers are different, one is a positive while the other one is a negative. So this problem can be changed to a subtraction problem. So start at 10 and subtract 4 to land on 6. Also, because 10 is a positive number we would start on the right side of the number line and move 4 places left and we would land on 6. With that being said 10 + (-4) = 6. Okay. Just so you know this is where I right my own answer. And I am open to suggestions. ^_^

Ok. Next question: Create a real-world problem that represents 2/3 and 2/5 . My answer: George ran 2/3 at the jog-a-thong. But his friend ran 2/5 at the jog-a-thong. How many laps did they complete all together? First, we need a common denominator. Which is 15 because both numbers go in to it evenly. Next, we need to correct the numerators because we changed the denominator. So 2/3 will become 10/15 and 2/5 will become 6/15. Then, we add these two fractions together to get 16/15 which can be turned in to a mixed number of 1 1/15. Lastly, our finally answer is 1 1/15.

Mmm you might want to change "jog-a-thong" to "jog-a-thon" xD Not sure if you know what a thong is, but.. you might want to change it. xD

Ok. Thanks! Next Question: Create a problem that uses the associative property to find the sum of at least 3 rational numbers. Show how the associative property is used to solve the problem. My answer: Associative property switches the order of groupings. A problem that uses the associative property is: 23 + (7 + 5)=(23 + 7) + 5 So first we do the grouping which is (7 + 5) this equals 12. Next, we want to add 23 and 12 together which give us the answer of 35. So the answer to the first part is 35. Next Part: First, we do the grouping of (23 + 7) which equals 30. Next, we add 30 and 5 which gives us the answer of 35. So both answers stay the same just different grouping.

Okay. Next Question: Apply the definition of subtraction and properties of operations to find the result. 1/9 - 4/5 - 1/9 My answer is: I need a little help on that one.
ShiBuringa
  • ShiBuringa
Well.. we first need to find a Common Denominator.
Miss.Rose
  • Miss.Rose
So 45?
ShiBuringa
  • ShiBuringa
Yep xP
ShiBuringa
  • ShiBuringa
So now we multiple each denominator by the number it needs to get to 45, thne do the same the top. :)

  • Miss.Rose
1/9 = 5/45 4/5 = 36/45
