Yes 1 5/7 and 4 2/7 is a solution. Adding those two numbers equals 6 because 5/7 + 2/7 = 1, then you have 4 + 1 +1 = 6
Two other solutions to x + y = 6 are any combinations of numbers when added together equal 6.
x = 5, y = 1
and
x = 2, y = 4
for the first question you would want to to multiply 52*1.5 because 52 is the original price and 1.5 is the mark up. by multiplying these together you get 78. next you need to add the tax. For tax you should multiply 78*.1 (this answer is 7.8) and add the answer to 78, getting the total of 85.8. I really hope this helps :-)
