#2801.35#

Explanation:

Decimals may be confusing at first, so you can use some of the properties of multiplication.

#156.6*17.9=((156.6*10)*(17.9*10))-:100#

You now have #(1566*179)/100#

Multiply normally to get #280314/100#

Since 100 has two zeros, move the decimal of your calculation two places to the left:

#2803.14#
