# Multiplying 2 fractions: fraction model

Visuals can be used to multiply fractions in a variety of ways, such as by using fraction models. By drawing rectangles and dividing them into equal parts, we can use an area model to multiply fractions. help to illustrate how the numerators and denominators of the two fractions interact to produce a product.

• Ok. When you are simplifying or dividing, keep these in mind:
Any even number is divisible by 2, so if both the numerator and the denominator are even, then you can continue to simplify it by 2.
If the digits of a number add up to a multiple of 3, then it is divisible by 3. So when both the numerator and denominator are multiples of 3, then you can simplify it by 3.
Numbers ending in 5 or 0 are divisible by 5.
You can just continue to simplify fractions with the 2, 3, and/or 5; these usually should be sufficient. And when two or more fractions are getting multiplied, you can take the numerator of one fraction and use it to simplify another fractions denominator (which will make the final multiplication easier). For example, if you have (5/8)x(2/3), then first simplify it to (5/4)x(1/3)heres a tip
• If the last two digits of a number are divisible by 4, then the number is divisible by 4.
If the number ends in 0, it is divisible by ten.
The three rule works for nine as well.
• I have no idea what he is talking about and I've watched this video 3 times
• It is pretty easy all you have to do is multiply both numerator and denominator.
• Is it possible to have a fraction as a numerator or denominator? Just curious.
• Yes, its possible. But it would be considered a complex fraction and would be simplified so the numerator & denominator became integers.

• pupusas con queso y salsa
• The translate of that is (pupusas with cheese and sauce).
{lol} like btw this is not a question
• I keep getting stuck on the practice problems even though I have watched it at least 5 times.
• Same ;-; I keep having the same problem and the calculator has failed me.
