Which is smaller 0.03 or 0.033?

Well, honey, let me break it down for you. 0.03 is smaller than 0.033 because the extra 0 at the end of 0.033 makes it bigger. It's like comparing a mini cupcake to a regular cupcake - one's just a tad bit smaller. So, in this case, 0.03 takes the cake for being the smaller number.
