Answer: 66/5 or 13 1/5
Step-by-step explanation: The first step in solving this problem is to create two fractions that can be multiplied together. So the first number will be an improper fraction, but that is what you need to do.
4 and 2/5 should be changed by multiplying the denominator (5) times the whole number (4). We get 20. Now we add the numerator (2). The new numerator is then 22. The denominator does not change. 22/5. The 3 can easily be made into a fraction by putting a whole in the denominator. The result is 3/1. Now you can multiply those two fractions together: numerators (22X3) and denominators (5X1). The result of that is 66/5. If your supposed to make it a mixed number, divide the top number by the bottom number (66/5) = 13 1/5.
