text: Normally I'd help out, but I don't think giving you the answers to 20 problems along with a description of how to solve them in the future would be worth the time.\n\nThe point of homework is to learn the methods.  These all involve adding or subtracting fractions and decimals.  It's an important concept to learn.\n\nThe main thing is to get your fractions with a common denominator, then it should be straightforward from there.\n\nIn the future, you may want to ask for the answer and method for a couple problems you have tried, and have someone check your work... but 20 questions for 10 pts (max) is too much work for anyone.
