Finals help

[RashadzMcCantz]

Have math finals tomorrow, need some help from some of you..How do you solve: (-3/4)(3)(-4)(1/3)only the 3/4 is like vertical and so is the 1/3I feel stupid for asking because this isn't that difficult but I kinda forgot how to do this since we learned it at the beginning of the year.

Just multiply the numbers together... I really don't know what else to say without actually giving you the answer though.

 

[yankshater213]

turn them all into fractions and multiply

(-3/4)(3)(-4)(1/3)so like-9/12 x 36/12 x -48/12 x 4/14 ???I'm having trouble getting the right answer.

 

[jonesboyz]

look at the numerators first and times them together:-3 x 3 x -4 x 1 = ?put that over the denominator which u do the same thing with on the bottom4 x 1 x 1 x 3 = ?that's your answer and reduce it if u can...if u know how.

Dude, just put in in your calculator with parenthesis.

 

[CRaZy_KiCkz]

you dont need to have the same denominator to multiply fractions

 

[RashadzMcCantz]

Thanks for the help!Now another question...-5=x-(-2)You have to like multiply by each side but how the hell would I do that?

 

[CRaZy_KiCkz]

subtract 2 to each side^ so it will be -7=x. x-(-2) is the same as x+2
