Answer:
68.048
Step-by-step explanation:
1. I ignored the decimal point and multipled the two numbers normally.
2. I counted the number of decimal places in the decimal numbers in the equation and added them up. The product after multiplication will have that number of decimal places.
3. I placed the decimal point the same amount of places as the number had.
I used a wiki how image and wrote a bit on it for further demonstration.
