    No. Your simply trying to figure out what 3/4 is of 15 1/2. Convert to decimal. 15.50 0.75 Multiply. 15.5 * .75 Convert to fraction.

    You would subtract if it asked how much she had left

    0.625 = 5/8. Your answer is 11 5/8 :)

    First, convert the fractions (15 1/2 & 3/4) to decimals. Then multiply the two together. (15.5 * .75) Then convert the decimal to a fraction. (11.625 = 11 5/8)

    If you don't want to convert to decimals and back into a fraction you can simply multiply the fractions. Whatever works best for you. Multiplying the fractions: Convert 15 1/2 to a improper fraction. = 31/2 Multiply 31/2 by 3/4. = 93/8 Covert/simplify that into a mixed number. = 11 5/8
