Step 1Multiplying two fractions is easier than adding them. You just multiply the numerators times each other, then do the same with the denominators. So we multiply 4 by 3, and get 12. Then we multiply 9 by 20, and get 180. And the result looks like this:

Step 2Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? To find out, we try dividing it by 2... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by 2 again... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by 2 again... Nope! So now we try the next greatest prime number, 3... Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
Let's try dividing by 3 again... No good. 3 is larger than 1. So we're done reducing. There you have it! The final answer is:
