Answer:
1 7/10
Step-by-step explanation:
First, you would convert the first mixed number into an improper fraction. In this case, it would be 17/4.
The next step would be to multiply the two fractions. To re elaborate, we would be multiplying 17/4 * 2/5. If you don't know how to do that, ask me.
The product is 34/20. It says to simplify the answer into a mixed number, so that would be 1 14/20, simplified to 1 7/10.
Hope this helps! :)
