Math Help... Fraction times x = number? What?

0	I am a little confused about how to do this. Here is a example that I made up. (Which could mean that it does not work but it will show the type of question.) 3/7x = 8 fractions help math asked Dec 16 '10 at 23:13 Madison Tries 6.1k●300●346●399

4 Answers:

If we are finding x, We move (3/7) over the equal.

This is a way by fraction busting.

(7/3)(3/7)x = 8 (7/3)

x=18.66667

I am not too sure of your math level, but you can also just divide each side by (3/7) and figure out x

That's how I would have done it.

3	Instead of doing it like Kevin I would find it easier to do: Then multiply the 7 over to get: or Then just divide by 3 to get: You shouldn't have to worry about calculating that to 18.6667, 56/3 is just as acceptable and is the exact answer. answered Dec 17 '10 at 09:27 recck 3.2k●3●22●52

0	basically you find the inverse of the faction (aka flip it). Then you multiple both sides by the inverse fraction. answered Dec 17 '10 at 12:30 FilipinoPower 13.0k●135●219●313 You mean reciprocal, not inverse. (Dec 17 '10 at 12:59) sfrancis928

0	3/7x = 8 you should multiply both sides by 7x to get 3=56x and now divide both sides by 56 to get x=3/56 this will be your answer. for more free math help logon to tutorvista.com answered Oct 19 '11 at 07:51 rattlesnake 1
