  1. Anyone can do this in their head.

    11 times 19 = 190 + 19 = 208

    Change this to 2.08 due to the decimals, and round!

  2. Hi Sean! Thanks for your reply. Your thinking is right on. You’d be surprised how many people miss this problem for one reason or another. 190 + 19 = 209, not 208…just a simple error. Really shouldn’t affect final answer. After rounding 2.08 and 2.09 to nearest tenth, both will become 2.1. D is the correct answer. Thanks again.
