    tricky ratio problem

    the ratio of the two numbers is 7:8. If their sum is 135, what is the bigger number?

    Re: tricky ratio problem

    Aren't you studying calculus? Because you've been posting calculus questions previously and now you're posting a really simple algebra question.

    Re: tricky ratio problem

    \frac{x}{y} = \frac{7}{8}

    x+y = 135

    same idea as your other post ... solve the system for x and y

    Yeah, you should probably review algebra before continuing on to calculus. It is almost impossible to pass a calculus class without a firm understanding of algebra.
