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
