If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to 3/4 or 75%
Hope this helps :)
Answer:

Step-by-step explanation:
To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

This is what I think your looking for
I believe the sum of the interior angles is the number of sides (n), subtracted by 2, and multiplied by 180.
(n - 2) x 180 = sum of interior angles of a n-gon
I also believe that the sum of exterior angles of a n-gon equals to 360 degrees.
Answer:
4 5/10
Step-by-step explanation:
Divide. You will have a remainder. Put the remainder over the denominator:
45/10 = 40/10 + 5/10 = 4 5/10
4 5/10 is your answer.
