A decimal number is simply a representation of a number such that the place value of each digit is ten times the place value of the digit to its right. It gives no information as to the location of the decimal point and so the number of decimal places.

8 and 6, respectively.

6 x 10-19 is the same as 6 x 1/1019. It is easier to understand the exponent as: "How many digits must I move the decimal point to the right (if positive) or to the left (if negative), to write the number out". In this case, move the decimal point (implied decimal point in this case; 6 = 6.0) 19 places to the left: 0.00000000000000000066 x 10-19 is the same as 6 x 1/1019. It is easier to understand the exponent as: "How many digits must I move the decimal point to the right (if positive) or to the left (if negative), to write the number out". In this case, move the decimal point (implied decimal point in this case; 6 = 6.0) 19 places to the left: 0.00000000000000000066 x 10-19 is the same as 6 x 1/1019.

In order to take a number to 2 decimal places, you first consider only the digits that are 2 decimal places in or greater. In this case that would be 2.73. The next step is to asses the thousandths digit. If it is 5, 6, 7, 8 or 9, we round up. Otherwise, we leave the number as it is. In this case, the digit is a 7, so we round up. Thus 2.73762 to 2 decimal places is 2.74
When multiplying one decimal by another decimal, the result will always have a larger number of digits to the right of the decimal point than either of the two factors. The number of digits to the right is the total of the digits for the two factors.Example:.25 x .3 = .075 (two digits plus one = three)You can make this clearer by putting all three in one of the numbers to start,making one of the factors a whole number..25 x .3 = .025 x 3 = .075Example:.02 x .03 = .0006 (the product is 6, the number of places is 4)In fraction form, this would be2/100 x 3/100 = 6/10000
