Answer:
19.5*0.6=11.4
Step-by-step explanation:
Set them up on top of each other and align the decimals. Add zeroes if needed. Then start with the lower right number, and multiply it by every number on top. Then go to the second lower right number, but first add a zero below the first part. Multiply the second number by al the other ones. Then add them all up. You get 11.4
