( How do you get 3/4 ) ( 2 and 1/2 ) converted to just numbers ? Also can you tell me how you did it. Thanks ! __________________ __________________ ( ( Crayola ( ( > http://www.microsoft.com/downloads/Search.aspx?displaylang=en http://www.microsoft.com/en/us/default.aspx http://support.microsoft.com/ http://en.wikipedia.org/wiki/Microsoft

However as boring as it seems, it is a must to master those sorts of things if you want to do something more interesting, like this: x = {q + [q2 + (r-p2)3]1/2}1/3 + {q - [q2 + (r-p2)3]1/2}1/3 + p where p = -b/(3a), q = p3 + (bc-3ad)/(6a2), r = c/(3a) AND: Sample standard deviation for a frequency distribution: __________________

well with fractions . 4/4 is the same as 1 so if you divide 1 by 4 you get 0.25 and the times that by the number on the top or to the left which in this case was 3 so 3X0.25=0.75.

That realy isnt helpfull or necesery , people have different levels of inteligence and different subjects they are good at . I am not very good at maths tbh but hey at least i tried to help the dude not just belittle him then brag about what you can do

Take the fraction that you want to make a decimal, ie, 3/4. Multiply it by a 100, so you get: 300/4 Then just divide 300 by 4, so you get 75. Then divide by 100 since you multiplied by it earlier, and voila, you get .75. With 2 1/2, think of it first as 2 wholes, so 2, then 1/2, do the same process, and get .5. Add .5 to 2 and you get 2.5. Those are useful tricks. __________________

You just reminded me why I hate math.

Nah its ok nobody is perfect . not even mods lol

but yeah thats the method my maths teacher taght me waay back and it is a good method and is kind of easy to work with whole numbers like 300's and 75's rather than than decimals

oi! worship the mods.. thou shalt be banned

or not.. im nice really

diffensials and integrals (apart from being impossible to spell) are a nightmare.. i spent most of this year doing them, lol, and im still useless.. most of the maths i use is electronics based.. like working out power consumption, current through components etc.. all good fun
