Answer:I won’t give you a full answer but I can explain it.
Step-by-step explanation: Our “goal” is $6.80 we have to figure out how many nickels and quarters are in it. First off, which is bigger? A quarter. Count as far as you can until you can’t go over 6.80. Now add the remaining numbers (the nickels) and you will have your answer. Make sure when your adding to count each quarter and nickel!
The reason for that is if u were to make 4/6 and 2/10 have the same denominator which would be 40/60 and 12/60 40 is greater than 12 and that fraction is equivalent to 4/6
