0.0777

Explanation:

1) Get rid of the decimals, by converting each number into a fraction:

#0.021 = 21/1000#

#3.7 = 37/10#

2) Multiply the two like you would multiply a fraction:

#21/1000*37/10 = 777/10000#

3) Do step 1 but in reverse to get from the fraction to the decimal:

#777/10000 = 0.0777#
