Answer: 1
Explanation:
there are two decimal places in total, keep that in mind
multiply everything by 10 to make whole numbers and multiply
4x25=100 because 4x5=20 and 4x20=4x10x2=80 and 20+80=100
remember those two decimals we counted, take that number, and move the decimal place over that many in your answer. 100 becomes 1
why not just use a calculator lol, you have internet access
