r%2F14-r%2F35=1%2F14 Start with the given equation.


70%28r%2Fcross%2814%29-r%2Fcross%2835%29%29=70%281%2Fcross%2814%29%29 Multiply both sides by the LCD 70 to clear any fractions.


5r-2r=5 Distribute and multiply.


3r=5 Combine like terms on the left side.


r=%285%29%2F%283%29 Divide both sides by 3 to isolate r.

Answer:

So the solution is r=5%2F3 which approximates to r=1.667.
