If you have mixed numbers, like 3 1/2 x 4 1/3, then you have to make those improper fractions first, then multiply straight across. Such as:

3 1/2 x 4 1/3 = 7/2 * 13/3 = (7*13)/(2*3) = 91/6. If your teacher requires mixed numbers for the answer, then you do that division:

91 `-:` 6 = 15 r1 = 15 1/6

For example:

`3/5xx2/27`

To multiply fractions, multiply the top numbers (numerators). Also, multiply the bottom numbers (denominators).

`=(3xx2)/(5xx27)`

Before multiplying them, cancel common factors between numerators and denominators. Since the numerator 3 and denominator 27 are multiples of 3, then cancel the factor 3.

`= (1xx2)/(5xx9)`

Now that the common factors are cancelled, proceed to multiply. And the resulting product is already in simplified form.

`=2/45`

Hence, `3/5xx2/27 =2/45` .
