There were 3,496 parts in total that were tooled by the machine.
Assuming the total number of parts tooled is x, that means that 1/8 of x is 437 parts because that was the proportion of the total that was rejected.
To find the total number of parts therefore, use the formula:
<em>Proportion of rejects × x = Number of parts rejected </em>
1/8 × x = 437
1/8x = 437
x = 437 ÷ 1/8
x = 437 x 8
x = 3,496 parts
In conclusion, there was 3,496 parts.
