Well, darling, the number 36.4375 has four decimal places. It's not rocket science, honey, just count those digits after the decimal point. So, in this case, you've got 4 decimal places to work with. Hope that clears things up for you!
If the exponent is positive, you move the decimal point to the right, the specified number of digits. For a negative exponent, you move it to the left. In either case, you fill out missing digits with zero. Examples (using "^" for power):3.448 x 10^1 = 34.485 x 10^6 = 5000000 (note the implied decimal point to the right of the number)3 x 10^-3 = 0.003
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.

You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
It is a decimal fraction.
The decimal part of a number are those digits to the right of the decimal point. In this case 5
It is a decimal fraction.
A real number. Or, the decimal representation of a real number.
The digits to the right of the decimal point. Ex: if you are given a number 283.7703, the decimal portion would be 7703.

The number of significant figures in a number is equal to the number of digits to the left of the decimal point up to the first leading zero. It is then added to the number of total digits to the right of the decimal point. In this case, there are six significant digits.
