Forums - General Discussion - DOES ANYONE KNOW HOW TO DIVIDE FRACTIONS(kills himself)

Hey are you doing umm the thing where you have to draw a line through the coordinate plane??? I remember that it starts with an "s"...I think...

 

EDIT: I remember now..It's called slope...Oh and what are you, in 10-11th grade??? Shouldn't you know how to do this already???

alright so to divide a fraction

lets say -2/3 divided by -3/5

you just turn it into

-2/3 times -5/3

and then its 10/3....?

 

 multiply the bottom(demonitator, can't spell today) and top part(numerator) to get 10/9.

negative * negative = positive

-3/5y=-2/3x + 5

multiply both sides by -5/3

-5/3*(-3/5)y = -5/3*(2/3x + 5)

y = -10/9x + -25/3

so m=-10/9 and b=-25/3



with any kind of fraction that you have, you have to divide the whole equation by the digits in front of the desired unknown.

so for -3/5y = -2/3x + 5 you divide by -3/5 and that gives you

y = 10/9x - 3 no problem

if say you have 4/5y = 1/2x + 10 you divide by 4/5 giving you

y= 5/8x + 8 etc etc. It's easy really, just get your head in the game. These are basics after all.



Huh. Who would've thought that beggining anew in my real life would coincide with starting anew on vgchartz?

Any day now, the dollar will be worth less than 2 zloty......any day now.....and my life savings will be in total jepordy ;(.

That would be correct.

When multiplying fractions you don't multiply the denominators, just the nominators so it would be 10/3.
