In order to solve this problem, we just have to multiply it normally. Firstly, remove the decimals first and proceed with the multiplication process.
786 x 46 would be 36156. Going back to the decimals, how many decimal places are there in total? So there are three decimal places. Now, from 6, count 3 backwards, and that makes 36.156. I hope that this answer helps. Let me know if you need more help next time.
