Convince me why you compared these two the way you did.
.590=.59
When looking on the right side of the decimal you look at each place value. They both have 5 tenths and they both have 9 hundredths. Adding a zero in the thousandths DOES NOT change the value of the number!

When you are rounding to the nearest hundredth I pay attention to the thousandths place. If the thousandths place is five or larger I round the hundredths place up, but if it is 4 or below I keep it low.
