    First, write 7 1/2 as a fraction. Then divide that fraction by 3/4.

    we can write this: \[\Large 7\;\frac{1}{2} = 7 + \frac{1}{2} = ...?\]

    To write a mixed numeral as a fraction, multiply the number by the denominator and add the numerator. That is the numerator of the fration. The denominator is the same you had.

    Ok. So far I changed the mixed numeral into a fractions. Now we need to divide a fraction by a fraction. Do you know how to divide a fraction by a fraction?

    To multiply fractions together, multiply together the numerators and multiply together the denominators. Then reduce if possible, To divide a fraction by a fraction, change the division into a multiplication by flipping the second fraction. Then multiply the fractions.
