Answer:
15 inches
Step-by-step explanation:
18/90= price for 18 inches.
To get to 75 cents, we have to make the top equal to 1. We can do this by dividing the numerator and denominator by 18. That leaves us with 1/5.
Now, we can multiply the top and bottom by 15. This is because 5 x 15= 75.
What you do to the bottom of the fraction you also do to the top. This leaves us with the answer: 15/75. That means you can buy 15 inches of wire for 75 cents.
