how to multiply multi digit numbers

25.04*3.005

the first one has 2 dp the second has 3 decimal places so the answer will have 5 decimal places

Now multiply ignoring the decimal places.

If you do not know how to do this look here

2504 * 3005

I will do it one the site calc.

$${\mathtt{2\,504}}{\mathtt{\,\times\,}}{\mathtt{3\,005}} = {\mathtt{7\,524\,520}}$$

we need the 5 decimal places (5 numbers after the point)

75.24520

We do not need the last 0 so the answer is

75.2452
