Question

Suppose that 12 inches of wire cost 48 cents at the same rate how many inches of wire can be bought for 28 cents

Answer 1

Answer:

7 in

Step-by-step explanation:

If 12 inches of wire can be bought for $0.48, we can set up the following ratio:

$\frac{12\text{ in}}{\ 0.48}$

Then, to determine how many inches of wire can be bought for $0.28, set up equivalent fractions, as such:

$\frac{12\text{ in}}{\ 0.48}=\frac{x}{\ 0.28}$

Then, cross-multiply and solve for $x$:

$\ 0.48x=(\ 0.28)(12)$

$\ 0.48x=\ 3.36$

$x=\frac{\ 3.36}{\ 0.48}$

$x=7$
