9.Solve for n. (7 and 5/6 + 5 and 2/3) + 9 and 1/3 = n + 15

Answer 1

Here's a tip for #6.... Plug those fractions into the calculator and you should get a decimal. You can then compare decimals to decimals and find the answer :P
#7.. A perimeter is basically just the addition of all the sides, so you can add 2(3 and 3/5) + 2(5 +2/3)
#8... You can get the common denominator for both and then add them
#9, same thing... Just get the common denominator and make those fractions one whole fraction.
