Answer 1

1.5 inches of steel is needed to make one string

Here, we want to know the number of inches of steel wire that is needed to amke one spring

Let the number be x;

We can have a relation as follows;

$\begin{gathered} 450\text{ inches = 300 strings} \\ x\text{ inches = 1 string} \\ \\ x\text{ }\times300\text{ = 450}\times1 \\ \\ 300x\text{ = 450} \\ \\ x\text{ = }\frac{450}{300} \\ \\ x\text{ = 1.5 inches} \end{gathered}$
