Are you sure your question starts with Why?
I believe it should start with what, if so then Z is the 100's
For your info: N is the thousand's, Z the hundred's, Q tenth & R the unit

We know that 172 of them were wood, so the rest are metal. To find that number we do:
276 - 172 = 104 metal pins.
To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:
104/276 is about 0.3768.
Multiply this by 100:
37.68
So, the percent of metal pins is 37.68%.
