A rational number can be expressed in the form a/b, where a and b are other integers. To satisfy this definition, 0.9 can be written as 9/10, 18/20, 90/100, etc.
"Per" essentially means "divided by." To find pieces per ounce, divide pieces by ounces.
(252 pieces)/(14 ounces) = (252/14) pieces/ounce = 18 pieces/ounce
The reason being is that we need to find it out of 100. So, we divide 400 by 4 and because we did that to the denominator we have to do it to the numerator so 16 divided by 4 is well 4. So we found out that is 4/100 we just divide that by 650 and we get 26.
TL;DR it’s $26
You are going to times 25.50 together and that's 51 so then you are going to divide 51.00 by 4.25 and that's 12
So the answer is 12
