Hey there!
Let's first simplify this product to see which two whole numbers it lies between. Remember, when we multiply fractions, we just multiply straight across. We have:
7/1 * 8/10 = 56/10
Now, we have to make it an improper fraction. 56 divided by 10 is 5 remainder 6, so we have:
5 6/10 = 5 3/5
Therefore, since it's after 5 but not 6, it's between 5 and 6. Hope this helps!
