The number of squares on a chess or checker board is 64 and to find the square root of 64 which is 8*8=64 so the answer is 8
Yes the quotient of 9 is rational
Add the 3 item totals, then divide that number by 100, then, take that number and multiply by 9 (this gets the tax total). then you are going to want to add the total of the 3 items, and the tax amount, and you have your answer. do this with all the peoples items :)
How I was taught: Make sure both numbers are a fraction. If not put "1" as the denominator. Multiply straight across. Simplify if you can.
