Can't see the questions clearly.

An advise:
Math isn't about the answer, it is about how you get to the answer (many ways).
For competitions like Kangaroo Math, you are not allowed to use calculators, think out of the box.

Please show some attempt at the problems yourself (or at least take a clearer picture or type up the problems so we can see what they are).
