Best ResponseYou've already chosen the best response.2from d down it was a bit hard to know what the question wassince you didn't use parenthesis.

Best ResponseYou've already chosen the best response.2d 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

Best ResponseYou've already chosen the best response.2for 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) \[\frac{15}{15}(s)  \frac2{15}(s) = \frac{152}{15}(s)==\frac{13}{15}(s)\] or \[\frac{13s}{15}\] thats how I like to work these, of courseif your way is easier for you and works, do that!

Best ResponseYou've already chosen the best response.0because: 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

Best ResponseYou've already chosen the best response.2Its 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: \[\frac6{4m}\frac3{4m}+\frac{m}8\] 63 = 3 so: \[\frac3{4m}+\frac{m}8\] although you can simplify this a bit, id leave it there and call that my answer.

Best ResponseYou've already chosen the best response.0what i dont get, is f) how is 4a/5 + 1/10 a is 7/10a. its 9/10a!!!

Best ResponseYou've already chosen the best response.0i solved it right, but for some reason i keep getting 9/10.

Best ResponseYou've already chosen the best response.0which is sad, cause i should know how to solve that.

Best ResponseYou've already chosen the best response.2combining \[\frac{4a}5+\frac1{10a}\] 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: \[\frac{18a^2}{10a}\]
