Please remember to write out the original problem. We do allow one exception and that is for a long worded problem; you only need to write some key words and numbers. You certainly are invited to write the entire problem.
On worded problems make sure you answer with a complete sentence and if measurements are involved, write units.

HW #4 Due on July 26, 2022
This week we covered fractions going over the essential parts of sections 2.1 through 2.6. I would like everyone to carefully read the following document and for those who missed Tuesday or Thursday of this week, the reading is critical.
https://www.pcc.edu/staff/wdiss/wp-content/uploads/sites/237/2020/02/Operations-On-Fractions.pdf
- 2.1: 1
- 2.1: 15 – 70 by 5, that is, 5, 10, 15, … 70
- 2.2: 1
- 2.2: 57 – 75 odd
- 2.3: 1
- 2.3: 25 – 50 by 5, that is 25, 30, … 50
- 2.3: 61 – 67 odd
- 2.4: 1, 71 – 73
- 2.5: 39 – 63 odd
- 2.6: 1
- 2.6: 57 – 73 odd
We will start in chapter 3 on adding and subtraction fractions on Tuesday, July 26, 2022. Please look at last set of steps and problem in the document:
https://www.pcc.edu/staff/wdiss/wp-content/uploads/sites/237/2020/02/Operations-On-Fractions.pdf
There are many similar steps in adding/subtracting fractions and in dividing/multiplying fractions. The big difference is that all fractions have to have the same denominator. We call this process finding the Lowest Common Denominator (LCD). Please read 3.2 and 3.3 carefully.
Lastly, I will be out of town on Tuesday, July 26, 2022 and possibly on Thursday, July 28, 2022. Please give the substitute your upmost respect and cooperation. Feel free to email me as I will be checking email on a regular basis.

- P. 215: 51 – 64
- P, 217: 1 – 30
- Test #2 on August 4, 2022 will be on fractions and decimals (Ch. 2, Ch 3, and part of Ch 4.)
The following document has a good overview of fractions and the necessary steps.
