Answer: 110

Turn each decimal into a Fraction

12.1 = 12 1/10

0.11 = 11/100

Turn 12 1/10 into an Improper Fraction

Multiply 12×10 and get 120. Now add 1 and get 121.

12 1/10 = 121/10

Do Keep Change Flip:

Keep: 121/10

Change: ÷ into ×

Flip: 11/100 into 100/11

New Problem: 121/10×100/11

Multiply

121/10×100/11=12100/110

Divide

12100÷110=110

Answer:


12.1 / 0.11 \\ (121)/(10) / (11)/(100) \\ (121)/(10) \ * (100)/(11) \\ 11 * 10 \\ 110
