    fraction multiplication

    In order to understand fraction multiplication thouroughly, we must be able to work simultaneously with different wholes using examples 3/5*3/4, explain why this is so. What are the different wholes that are associated with the fractions in the problem 3/5*3/4(including the answer to the problem?



    Please help.

    What are wholes? Do you mean integers? i.e. whole numbers???

    (3/5)(3/4) = 9/20

    So the integers associated with it are 3, 4, 5, 9 and 20, no? Is that what you meant?

    Can you state the problem exactly as it is written? I think you mean what whole numbers do you multiply together in the fractions (numerators and denominators) to obtain the product, which is itself a fraction made up of a whole number numerator and denominator. Right?

    \frac{3}{5}\cdot\frac{3}{4}=\frac{3\cdot3}{5\cdot4  }=\frac{9}{20}

    The problem is exactly what I wrote. I am also very confused with the question, What you wrote make sense but. I think all they want are the different wholes associated with the fractions in the problem 3/5*3/4.

    Thank you
