Question

A worker uses 750 inches of steel wire to make 300 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?​

Answer 1

Answer:

2.5 inches

Step-by-step explanation:

750inches=300 units

1 unit= 750/300=5/2=2.5

therefore one spring requires 2.5 inches of steel wire

Answer 2

$\huge{\underline{\texttt{\red{Answer:}}}}$ 2.5 inches

$\huge{\underline{\texttt{\red{Solution:}}}}$

We know that,

A worker uses 750 inches of steel wire to make 300 springs.

$\therefore$ By using proportion, we will find out how many inches of steel wire are needed to make 1 spring.

Let x be the inches of steel wire needed.

$\implies$ $\frac{750\: inches}{300\: springs}$ = $\frac{x\: inches}{1\: spring}$

$\implies$ x = $\frac{750\: inches}{300\: springs}$ × 1

$\implies$ x = 2.5 × 1

$\therefore$ x = 2.5 inches
