I tend to use the blog (when studying) for things I need to memorize. I don't work through *how* to do the problems or complexities. I just focus on the basics of memorization here, while doing the rest of my studies on paper. Interesting.
Anyway, along those lines, my study guide recommends memorizing common fractions and decimals in the form of percentages in order to easily eliminate answers that are particularly off the mark.
Some are things I've naturally memorized in the course of my life, and I am sure you have too:
- 1.0 = 1/1 = 100%
- 2.0 = 2/1 = 200%
- 0.25 = 1/4 = 25%
- 0.5 = 1/2 = 50%
- 0.75 = 3/4 = 75%
Some are very familiar and perhaps already somewhat memorized, or easy to quickly figure out, even if I have to review them in order to recommit them to memory:
- 0.01 = 1/100 = 1%
- 0.1 = 1/10 = 10%
- 0.2 = 1/5 = 20%
- 0.4 = 2/5 = 40%
- 0.8 = 4/5 = 80%
Others I need to spend just a tad more time on to truly memorize:
- 0.333 = 1/3 (that part is familiar) = 33 1/3% (that I didn't realize)
- 0.6 = 3/5 (that part I would have had to calculate) = 60% (this I knew)
- 0.666... = 2/3 (that part is somewhat familiar) = 66 2/3% (that I didn't know)
