Simplify: 310+9.7 Simplify: 2+3.10 divided by 5.39 Simplify: 1610 divided by 5+13

310+9.7 = 310+63 = 7+63 = 56
(2+3.10)/(5.39) = (2+30)/(159) = 32/6 = 16/3
(1610)/(5+13) = 6/18 = 1/3
when you have fractions, the numerator and denominator must be evaluated separately, then finally divided. 
thanks Steve,but the second one still don't get it right

so, what do you get? If you have trouble, it's much better to show your work, so we can set things straight.
