> > sigh. it is the conversions that are getting me... converting fractions to decimals... there are things that are Handy To Know: like 8 x 125 = 1,000 and something... something about 3,125 and 100,000... I guess I just need to put in the time... And that will help me with figuring out which percentage of which number is most...

> Probably easiest to memorize the numbers 1/2-1/10. 1/2=0.5, 1/3=0.33 and so on.yes. i have some memorized. but i think maybe what it wants me to memorise is even f*ck*ng more times tables. e.g., 25x4 = 100. so any fraction with 4 on the bottom will go into a decimal to the hundredth place.
e.g., 3/4 = .75
because 4x25=100
and so 3x25=75
so 75/100
so .75i think 125 is a magic number, too. that gets us to the thousandth place something to do with 8...
and there is a magic number to get to the ten-thousandths place...
anyway... i need to look into it... ratios and proportions here i come. sigh.
class started back today YAY! i really was bored... conversions and moles... i'm okay because i prepared well over the break. but i'd be f*ck*ng lost otherwise. she's fairly... uh.. methodical.. uh.. it isn't the most exciting subject matter to be sure.. anyway... will be okay...
lots of equations for me...
