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.
