Final answer:
You can make 459 4-inch nails from 51 yards of steel by converting the total yards to inches and then dividing by the length of one nail.
Step-by-step explanation:
To calculate how many 4-inch nails can be pressed from 51 yards of steel, we first need to convert the total length of steel from yards to inches, since the length of a single nail is given in inches. There are 36 inches in a yard, so we multiply 51 yards by 36 to find the total length in inches:
51 yards × 36 inches/yard = 1836 inches
Now that we have the total length of steel in inches, we can divide this number by the length of one nail to find the number of nails:
1836 inches ÷ 4 inches/nail = 459 nails
Therefore, the machine press can make 459 4-inch nails from 51 yards of steel.
