    It's stoichiometry. Find common units and cancel them out for the desired answer.

    Method I - Set up a proportion

    x words/ 5 minutes = 180words / 2minutes

    Multiply both sides by 5 minutes

    x words = 180words / 2minutes * 5 minutes

    x words = 450 words <––––––

    ----------------------------

    Method II - Rate

    Calculate the rate , ie. number of words per minute

    180 words/ 2minutes = 90 words / minute

    multiply the rate by the time

    90 words/ minute * 5 minutes = 450 words

    450 words <––––––
