For this you will have to know how to add fractions. First of all i like to add the whole numbers together first, so 2+2+3= 7. so now what you have to do is add the fractions together. so    2/3 + 1/4 + 1/2 = ?   you will have to find a common denominator for 3, 4, and 2; which is 12.  Multiply each fraction by the needed number to get each denominator to 12. so 2/3 will be multiplied by 4, 1/4 will be multiplied by 3, and 1/2 will be multiplied by 6. The new equation and answer will be:   8/12 + 3/12 + 6/12 = 17/12. 17/12 as a mixed fraction is 1 5/12. now we add 1 5/12 and 7 to equal 8 5/12.  and then you will have to subtract this from 10, using common denominators and such to get your final answer of  2 1/12.   (sorry for the long spiel on how to do this question)
