Well, honey, first you multiply 7.8 by 3 to get 23.4, then you move the decimal two places to the left because you're multiplying by 0.03, giving you a final answer of 0.234. It's as simple as that, darling. Math doesn't have to be a headache if you just tackle it head-on.
When doing it by pencil and paper (or mentally):
1) ignoring the decimal points multiply the numbers together;
2) count how many digits in total are after the decimal points in the multiplication;
3) put the decimal point into the answer (inserting leading zeros if necessary) so that the same number of digits follow the decimal point;
4) any trailing zeros can be not written.
For 7.8 × 0.03 this leads to:
78 × 3 = 234
in 7.8 there is 1 digit after the decimal point
in 0.03 there are 2 digits after the decimal point
Thus in 7.8 × 0.03 there are 1 + 2 = 3 digits in total after the decimal point, and the answer must also have 3 digits after the decimal point.
→ 7.8 × 0.03 = 0.234
If the question had been 0.05 × 0.4 this leads to:
5 × 4 = 20
0.05 × 0.4 has 2 + 1 = 3 digits after the decimal point
Thus 0.05 × 0.4 = 0.020 which has 3 digits after the decimal point but would [normally] be written without the trailing zero as 0.02 (only having 2 digits after the decimal point).
