Percentages are easy to represent as decimals. Just remember this: If the value is under 100%, just place a decimal point in front of the percent value and remove the percentage sign. If it's over 100%, you'd put the decimal after whatever is in the hundreds place. The reason you can do this is because percent represents a value out of one hundred, and decimals do the same representing values as part of one.
So, 39%->.39
You would add the 2 fractions. Since 2/16 equals 1/8 you could add 1/8 plus 4/8. That will give you 5/8. After all that you subtract 5/8 from 8/8, which will give you 3/8.
