Problem Solving #1

I love math(sort of). Math is cool. This is a math problem that I did:
3. The value of 2 1/10+ 3 11/100 + 4 111/1000 is

(A) 9. 321 (B) 9.111 (C) 9.123 (D) 9.111111 (E) 9.11081081

The first step in solving this equation is to make the three denominators the same. To do that, you should multiply 2 1/10 by 100 to make the denominator 1000, resulting in 2 100/1000. Secondly, you multiply 3 11/100 by 10 to make it 3 110/1000. After that, you can add the three numbers together and the answer will be 9 321/1000. Finally, you change the number into a decimal. The final answer is A- 9.321. :)
