Three. All non-zero digits are significant, all zeroes between other digits, and all digits to the right of the decimal. The reason for this is that if this is rounded off, it apparently is rounded off to the nearest tenth, otherwise the tenth place would not be shown. if it were rounded off to the unit, it would read 39, not 39.0 ■
It mean to add more decimal places to a value. Sometimes this will show a more accurate value, rather than a rounded up value which is being shown because there are not enough decimal places to show the value in full.
As shown, a terminating decimal.
It is 4.80 and not 4.79 ---------------------------- The thousandth digit is a 5 so round up: 4.7958 → 4.80 to the nearest hundredth Note: 4.8 and 4.80 are the same value, BUT as it has been rounded to the nearest hundredth, the hundredths need to be shown, so it is 4.80 and not 4.8
It is: 1/20 = 0.05 as a decimal
The answer is 52.8 as 52.752 is only0.048 away from 52.8 whereas it isa bigger 0.052 away from 52.7 so thesmaller number is chosen.
It is 0.6666 (6 repeated infinitely, usually shown as 0.66, with a bar notation above the 6). Typically this is rounded to either 0.67 or 0.667.
It is usually a fraction, as it is usually shown in a ratio. Decimal and percentages can be used though.
A repeating decimal is usually shown with a bar over the decimal that is repeated
