Answer:
30.85
Explanation:
1. Put the 12.34 on top to make things simpler
then just multiply each number as if the decimals weren't there to begin with.
Your answer should look way too big, but when you finish multiplying count how many decimal places were in the two numbers, for this it would be 3 since there is a 5, 3, and 4 behind the decimal places.
You have to count 3 decimal places in your final answer to get the right solution! Any 0's trailing behind can be removed as well.
Hope this helps!!!
