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
