    The answer should be 21 and 45, written as 21/45. Do you understand how I got that?

    Well I got 63/15 because 7*9 is 63 and 5 time 3 is 15. all I have to do is convert. But I guess I got it wrong.

    \[-\frac{7}{\cancel{9}^3}\times \frac{\cancel 3^1}{5}=-\frac{7}{15}\]

    Oh, there's the issue. You're supposed to multiply the top numbers (numerators) and the bottom numbers (denominators) together, not the same ones on the fraction.

    First, convert the mixed number into a fraction form so you can multiply it. Do you know how to do that?

    Correct. Now what's 8/3 * 9/1?

    Nono, you're supposed to multiply like this: \[\frac{ 8 }{ 3 } * \frac{ 9 }{ 1 }\]

    Multiply 8 * 9 and then 3 * 1

    It wouldn't be a mixed number in this case, because 72/3= 24

    Basically, the fraction means divide, so \[\frac{ 72 }{ 3 } = 24\]
