Mulitply the numerators and the denominators. Example: 5/3 x 7/5. First, you would multiply 5 and 7 to get the numerator of the product, which is 35. Then you would multiply 3 and 5 to get the denominator of the product, which is 15. The answer is 35/15 or 1 1/3 which is in simplest form. In order to find the answer in simplest form, you would find how many times the denominator goes into the numerater, which in this case, would be 1 with 5/15 leftover. But now, 1 5/15 can be simplified again to 1 1/3 by finding the least common multiple of 5 and 15, which is 5, so you would divide both 5 and 15 by 5 to get 1/3. The answer for this scenario would be 1 1/3.

Why do you write a mixed numbers into inproper fractions?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
How do you change an mixed number in a inproper fractions?
All you need to do is this Example: 3 1/2 You need to multiply 3 time 2 and then add one and keep the 2 on the bottom. This would equal: 7/2 (seven over two)
Why do you invert fractions?
When you divide by fractions, you invert and multiply.
When you multiply fractions do you multiply the denominator?
yes. you multiply the numerator and denominator
