Hello! To answer your question, on how much farther Payton drives than Jesse, you need to understand the needed operation for this problem. From the given problem, you can assume that 7 3/4 is a bigger fraction than Jesse's 6 3/8. Once you figure out which operation is needed to find out how much more Peyton drove, you want to make both mixed numbers into inproper fractions. To make a mixed number into an improper fraction, you multiple the whole number by the denometer and add the product to the numeratior. Think of it as going around a clock if that helps. Once they are both improper, give them both a common denometer (if needed). Once you do that, you use the operation you decided on earlier; multiplication, division, addition, or subtraction. If you have any other questions on my answer, or any information I've given, feel free to shoot me a message or another question. I hope this helped, good luck!
