Answer:

Step-by-step explanation:

Turn the second part into an improper fraction by multiplying the coefficient (the big 3) by the denominator of the fraction. You should get 3*3 = 9. Then add that number to the numerator of the fraction to get this:

Now, multiply directly across, so 8*10 over 15*3.
Now multiply out: 
You can simplify this into
Now, see how many times the denominator goes into the numerator evenly (1 time) and subtract that from the numerator to get
