Okay, here are the instructions Mr.Harbeck gave us, for this assignment:
1) Explain how to add and subtract fractions.
- Give 3 examples: one has to be a mixed fraction.
2) Explain how to multiply fractions.
- Give 2 examples: one has to be used with proper fractions and the other with mixed fractions.
3) Explain how to divide fractions.
- Show with both proper and mixed fractions
4) Solve 2/3 word problems that he gave us.
- Show all of your work.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1) Explain how to add and subtract fractions.
- Give 3 examples: one has to be a mixed fraction.

Here are 10 easy steps on how to do it. Although, some steps aren't nessessary, depending on what kind of question you're dealing with.
1) write down the question
2) add/subtract the whole numbers
3) put the sum/difference on the other side of the equal sign
4) if the denominators aren't the same, you need to find the LCD (Least Common Denominator)
- find the multiples for each denominator until you get a number that both denominators have
5) for both sides of the equal sign, do this: (LCD/D)N=NN
- Least Common Denominator divided by Denominator times Numerator equals New Numerator
6) add/subtract the fractions
7) if the sum/difference is an improper fraction, convert it into a mixed number
- divide the numerator by the denominator (subtraction doesn't always work)
- instead of having a remainder, that number will be the numerator
- rewrite your mixed fraction

8) now just add this sum/difference to your whole number on the other side of the equal sign
9) simplify if nessessary
10) there's your answer
*simplifying basically means to make the pieces of the whole smaller*
Reminders:
- if the question you're answering, is a word problem, don't forget the simple sentence
- if there's a unit, don't forget it in your simple sentence
- if there are brackets in the question, do them first before you do the outside
- if you're adding more than 2 fractions, use the same steps, and make sure you find the LCD for all of the fractions

Now here are 3 examples:

2) Explain how to multiply fractions.
- Give 2 examples: one has to be used with proper fractions and the other with mixed fractions.

Here are 8 easy steps on how to do it. Although, some steps aren't nessessary, depending on what kind of question you're dealing with.
1) write down the question
2) if you're multiplying a whole number by a fraction, that number will be the numerator, and the denominator is one
3) if you're multiplying mixed fractions, convert them into improper fractions
4) multiply the numerators
5) multiply the denominators
6) simplify if nessessary
7) if your final answer is an improper fraction, convert it back into a mixed fraction
8) there's your answer
Optional: draw pictures

Reminders:
- if the question you're answering, is a word problem, don't forget the simple sentence
- if there's a unit, don't forget it in your simple sentence
- if there are brackets in the question, do them first before you do the outside
- if you're multiplying more than 2 fractions, use the same steps

Now here are 2 examples:

3) Explain how to divide fractions.
- Show with both proper and mixed fractions

Here are 8 easy steps on how to do it:
1) write the question vertically
2) if you're dividing with mixed fractions, convert them into improper fractions
3) if you're dividing with a whole number, that number will be the numerator, and the denominator is one
4) find the reciprical of the divisor
5) multiply the reciprical by the dividend
6) multiply both top and bottom
7) simplify if nessessary
8) if your final answer is an improper fraction, convert it back into a mixed fraction

Reminders:
- if the question you're answering, is a word problem, don't forget the simple sentence
- if there's a unit, don't forget it in your simple sentence
Now here are 2 examples:









~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

4) Solve 2/3 word problems that he gave us.
- Show all of your work.
Here are the 2 word problems I've chosen to share with you:






























Finally, I'm finished. Well, thanks for checking out my last fraction post.
Well, I hope you all understood this (:
