a) \[\frac{5k}6\] b) \[\frac7{10x}\] c) \[\frac5{8z}\] d) \[\frac{13s}{15}\] e) \[\frac{m}{8}-\frac{1}{4m}\] f) \[\frac1{10a}-\frac{19a}5\]

okay... well for a b and c i have the same. for d i have - 17/15s. for e i have 6/8m. for f i have - 3 and 9/10a
hihi67
  • hihi67
this is how i figured it out. d:
agreene
  • agreene
from d down it was a bit hard to know what the question was--since you didn't use parenthesis.
hihi67
  • hihi67
no () in book either.
hihi67
  • hihi67
ust a min.
agreene
  • agreene
d could have been: \[\frac{s}5 - \frac{s}3 + s\] which is what i assumed, or \[\frac{s}5-\frac{s}{3+s}\] which would be a harder problem, lol
hihi67
  • hihi67
\[s/5 - s/3 + s : \space \space \space \space \space \space \space \space \space s-5-s/3 = 3s/15 - 5s/15 \space \space \space that equals -2s/15 \space \space \space \space \space -2s/15 + s = \]

  • hihi67
thats d
hihi67
  • hihi67
dang cant see it.
hihi67
  • hihi67
never mind...
hihi67
  • hihi67
bye thanks

lol dont give up so quickly :P

  • hihi67
ooooh I KNOW!

  • hihi67
stupid "order of operations"
hihi67
  • hihi67
yep, thanks! you really actually did help a lot!!!

for d: I find it easier to start by factoring out the variables (makes it easier for me to see): s/5 - s/3 +s \[\frac15(s) - \frac13(s)+ s\] combine your fractions: \[-\frac2{15}(s)+s\] combine those fractions (convert the +s to +15s/15 so its the same denominator) \[\frac{15}{15}(s) - \frac2{15}(s) = \frac{15-2}{15}(s)==\frac{13}{15}(s)\] or \[\frac{13s}{15}\] thats how I like to work these, of course--if your way is easier for you and works, do that!
hihi67
  • hihi67
you are very much a genius. that really helps!!!! you should become my math teacher!
hihi67
  • hihi67
hah
hihi67
  • hihi67
what about for e?
hihi67
  • hihi67
e is 7/8m
hihi67
  • hihi67
because: 1 1/2m is 3/2m and 3/4 m, normal. m/8 = 1/8 times m. 3/2 time m - 3/4 times m is 3/4 times m. 3/4 time m - 1/8 times m is 7/8
agreene
  • agreene
Its a little bit harder, but: I'd start by converting that mixed fraction in the front, 1 1/2 = 3/2 so 1 1/(2m) = 3/(2m) that gives us: \[\frac3{2m}-\frac3{4m}+\frac{m}8\] convert that 2m denominator to 4m by multiplying 2/2 through it: \[\frac6{4m}-\frac3{4m}+\frac{m}8\] 6-3 = 3 so: \[\frac3{4m}+\frac{m}8\] although you can simplify this a bit, id leave it there and call that my answer.

  • hihi67
okay..
hihi67
  • hihi67
what i dont get, is f) how is -4a/5 + 1/10 a is -7/10a. its -9/10a!!!
hihi67
  • hihi67
i solved it right, but for some reason i keep getting -9/10.
hihi67
  • hihi67
which is sad, cause i should know how to solve that.
agreene
  • agreene
combining \[\frac{-4a}5+\frac1{10a}\] is a bit tricky, in fact in my first answer, i didn't even do it. the reason is the variable is in the numerator of one and the denominator of the other... if you would like to do it, remember you need to multiply through and get the same denominator... in this case: 10a is what we need. 5 is what we have, so we need to multiply through 2a to the fraction on the left: \[\frac{-4a}{5}*\frac{2a}{2a}+\frac1{10a}\] \[\frac{-8a^2}{10a}+\frac1{10a}\] now we can combine these two, since they have the same denominator: \[\frac{1-8a^2}{10a}\]
hihi67
  • hihi67
oh. i just did 5 * 2 is 10. -4a * 2 is 8!
agreene
  • agreene
yeah this one is a bit more tricky :P
hihi67
  • hihi67
okay. thank!
hihi67
  • hihi67
you
hihi67
  • hihi67
bye now!
