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
