Will someone me with this one i'm not good at simplifying

0.04(0.7)= its multiplication. you multiply them together as a normal number without the decimal and then add the decimals after.
so it would be .04x.7 
7x4=28
so it would be 0.028 because there are three numbers behind the decimal point in both numbers being multiplied. 

1.8(0.3)= you do same thing with this one.
3x18=54
since there is 2 numbers behind the decimal the answer is 0.54

So confused right here i need it to be more clearer
