I can see how this might be a little confusing. The key is in what you are counting.

When you were counting the worth of the dimes [1-ten cents (one dime), 2-ten cents (two dimes), etc.] It was in the value of cents.

When asked how many dimes are in 2 dollars, The answer is the number of dimes. It may help to add the word dimes to your answer. You need 10 dimes to make a dollar, 2-ten dimes to make 2 dollars and 3-ten dimes to make 3 dollars.

HTH,

Valerie's right. If you think about it, by your logic of "20-ten cents" for two dollars, then the answer for one dollar would be TEN-ten cents, not just ONE-ten cents.

So while you're correct that one dime equals 1-ten cents (and that's a good way to count it when showing the value of a dime), the question isn't how many CENTS are in 2 dollars, but how many DIMES. 20 dimes, which in 'math language' is 2-10 dimes.

Hello Venla,

After looking into this and speaking with you. I will advise to have the words 2-ten dimes added in the text.
