Simply enough, divide. Example 1: What is 105/7? Well, since 7 goes into 10 once, remainder 3, and into 35 five times, the answer is 15. Example 2: What is 150/13? We divide 15/13 and get 1, remainder 2. "Bring down" the 2, and we divide 20/13 and get 1, remainder 7. So the answer is 11 7/13.

Steps for multipling fractions and mixed numbers?
to multiply fractions add them together and reduce the final fraction. to multiply mixed numbers, first make the mixed number an improper fraction, by mulitplying the whole number and the denominator and adding the answer to the numerator. Example: The improper fraction 8/5 can be changed to the mixed number 1 3/5 by dividing the numerator (8) by the denominator (5). This gives a quotient of 1 and a remainder of 3. The remainder is placed over the divisor (5).
Why is it important to change mixed number to improper fraction?
When you are multiplying with mixed number fractions, it becomes easier to work with improper fractions instead. For example, 2 1/3 x 1 1/2 (two and a third times one and a half) is 2 x 1 + 2 x 1/2 + 1/3 x 1 + 1/3 x 1/2 But with improper fractions, it's 7/3 x 3/2 = 7/2 = 3 1/2
