Evertight, a leading manufacturer of quality nails, produces 1-, 2-, 3-, 4-, and 5-inch nails
for various uses. In the production process, if there is an overrun or the nails are slightly defective,
they are placed in a common bin. Yesterday, 651 of the 1-inch nails, 243 of the 2-inch nails,
41 of the 3-inch nails, 451 of the 4-inch nails, and 333 of the 5-inch nails were placed in the bin.

(a) P =  .
(b) P =  .
(c) P =  .
Everything is so clear in this problem that more detailed explanations are excessive.
The formulas are SELF-EXPLANATORY.
If you have questions, look and hear attentively what these formulas tell you.

Part (a)
A = 651 = number of 1-inch nails
B = 243 = number of 2-inch nails
C = 41 = number of 3-inch nails
D = 451 = number of 4-inch nails
E = 333 = number of 5-inch nails
A+B+C+D+E = 651+243+41+451+333 = 1719 nails total
Of that total, D = 451 are four-inch nails.
Answer: 451/1719
==========================================================================================
Part (b)
We use the same idea as part (a)
E = 333 = number of five inch nails
A+B+C+D+E = 1719 nails total
It leads to the fraction 333/1719 which reduces to 37/191 after dividing both parts by the GCF 9.
Answer: 37/191
==========================================================================================
Part (c)
The question is cut off. Please repost. Thank you.
