Question

Suppose that 17 inches of wire costs 85 cents. At the same rate, how many inches of wire can be bought for 65 cents?

Answer 1

Answer: 13 inches

Explanation:

To solve this problem you would need to make a ratio.

A Ratio can be the symbol, : , / or the word to.

In this case you would need to do the problem as shown:

17/85 = x/65

First you would need to cross multiply, then flip the equation. And should end up with something like this:

85x =1105

Then Divide both sides by 85.

85x/85 = 1105/85

Answer:

X= 13

Answer 2

13 inches

Explanation:

17=85

1=85/17

1=5

Now

For 65 cents,

65=nx5

65/5=n

n=13 inches
