Fractions in Life

I never really thought about fractions in my life, but after reading your blog, I see that I use them almost everyday without even thinking about it. Often times I automatically resort to fractions to see how much progress I have made. This happens in running and when I see that I'm almost 1/2 done with the run, I use that to push myself to finish that last half. 

Similarly, over the summer I found myself using this subconsciously using fractions to get through the day. During the summer I worked on campus in grounds keeping. It was a long day but after each hour I could mark that I was 1/7 done. With a break at 10:00 and then an hour off for lunch, I would break up the day into thirds rather than sevenths (I would not count the lunch). When it was time for break I would be 1/3 of the way done, then when I was at lunch I would be 2/3 done with the day.

I would also divide up my work into fractions, giving 1/2 of the area we had to rake to my partner and then 1/2 for myself. I would calculate how much I could get done and often times find myself aiming for a specific fraction. An example would be striving myself to finish 1/3 of the weeds by break time so that I could finish another 1/3 by lunch and then hopefully finish up the last third by the end of the day.

9%

The idea of a grade in the road is called the slope (known as rise over run, a bigger number means a higher or steeper slope of the surface compared to it being flat, or horizontal. Slopes are seen everyday in life; just recently our class studied trigonometric functions and finding the length of a side in a right triangle given an angle and the length of a side, or finding the angle of the slope and given the length of two sides, finding both solutions when plugged into the right equation.

Slopes can be found in our lives such as when we drive along hills, using less gas and simply letting the car go on its own when we have a steep hill, or using a lot when we go up a hill. The amount of slope or "grade" can also be seen directly at school as we occasionally have large thunderstorms, flooding our lower campus due to the gradual but large steepness of the school.
