How would you make 300ml of a mixture of toluene and hexane in a ratio of 70:30 respectively?

~I really don't know how I would do this...would I do this?:

xT + yH= 300ml

xT= 300ml- yH

then plug that in? That came out funny though since I get 0 in the end...

~Help Please~

Thanks

    I assume this is a volume ratio.
    70 + 30 per 100 mL.
    270 + 90 per 300 mL.

    Oh..so that's how that works..

    Thank you Dr.Bob =)
