Ed is traveling at 63 miles per hour so it will have a variable. He already drove 242 miles, and is planning to drive 668 miles. Because the goal is 668, this whole equation equals 668.
Fractions are just unsimplified numbers. For example 5/8 is just 5 divided by 8 so 0.625. To find the percent from that you move the decimal two places to the right making it 62.5%. Hope this helps!
