Where is the decimal point in a whole number?
If you must have it, it is after the right-most digit.
How Do you round 1.978 to one decimal place?
2.0The first digit after the decimal point is "9". We now look at the second digit after the decimal point. As this is "7", which is greater than or equal to "5", we must round the "9" up (we make the number larger).This makes the "9" become a "0" and to make this number larger we must also therefore make the "1" into a "2". This is because the "9" has actually become a "10" and so we have to add "1" to the digit to the left (1 + 1 = 2).
How is 17 thousandths has more than two places to the right of the decimal point?
The first place after the decimal point is tenths. The second place after the decimal point is hundredths The third place after the decimal point is thousandths. So the number must extend to the third place after the decimal.
How do you do a stem and leaf plot with fractions and whole numbers mixed together?
You round the fractions to decimal numbers to a suitable number of decimal digits. Then create a stem and leaf plot using these numbers - ignoring the decimal point, except that you must make sure you mention it in the key.
When writing a number in scientific notation how many digits should be left on the decimal point?
Only on digit may be to the left of the decimal point. The mantissa must be a number in the interval [0, 10).

How do you estimate a decimal?
1. You must first go to the place in front of the decimal and round that number 2. Do the same for the next number 3. Lastly do the operation to find your answer

What do you do if there is an whole number in an adding and subtractingdecimal problem?
You can add or subtract it as a whole number. If you must use its decimal form, you just stick a decimal point at the end the whole number!
What is the answer if you round this 32.5219?
You round up if a number is 5 or more. You start at the right. So9 is more than 5, round up. The 1 becomes 2. Two is less than 5; the 2 remains the same. Therefore, start with the next number, the 2. Again, it is less than 5. If you are supposed to round but keep the decimal point, it would be 32.5. If you must round to a full number, it is 32.
When writing a decimal number less than 1 you must apply the?
decimal point to the left of the whole number. Example: 1= whole number. Less than 1 as a decimal is .00, .01, 02 etc.
When multiplying decimals where do you move the decimal?
the answer is it stays in the same place.* * * * *Not quite.Suppose you want to multiply two decimal numbers A and B. Multiply the two numbers ignoring the decimal points.Count the number of digits after the decimal point in the number A.Count the number of digits after the decimal point in the number B.Add these two numbers together. This is the number of digits you want after the decimal point in the answer. So count back from the end.Example:2.54 * 3.5 (this is number of centimetres in 3.5 inches)254*35 = 8890Number of digits after the decimal point in 2.54 is 2 (5 and 4).Number of digits after the decimal point in 3.5 is 1 (5).2 + 1 = 3 so there must be 3 digits after the decimal point in the answer.Therefore 8890 becomes 8.890NOW, you can simplify it to 8.89
How do you write 23789000 in scientific notation?
Move the decimal point left seven places so that there is one digit before the decimal. Because the decimal point was moved left seven places, the new number must be multiplied by 107: 2.3789 x 107 (The zeros are not needed because they are at the end of the number and are after the decimal point.)
How do you round 13.681 to one decimal place?
To round 13.681 to once decimal place, you first need to look at the second decimal place and determine it's value. If the number is less than five, you will keep the number that is in the first decimal place. In this case, the number in the hundredths (second) position is an eight, which is greater than five. Therefore, we must change the six to a seven. The answer would be: 13.7
