When a number is rounded to to decimal places the result is 13.55 What are 6 numbers which could have been the original number?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1".
13.55 (2dp) can be obtained from numbers with 3 decimal places ranging from 13.545 to 13.554.
Six possibilities for the original number are 13.545, 13.547, 13.549, 13.551, 13.552, 13.554.
NOTE : If the choice of original numbers were extended to numbers having (say) 6 decimal places of figures then the six possible numbers could have been chosen from the range 13.545001 to 13.554999

What is a decimal number changed to 23.7 after it was rounded?
To determine the original decimal number that was rounded to 23.7, we need to consider the place value of the digit 7. In 23.7, the 7 is in the tenths place. If we round 23.7 to the nearest whole number, it would be 24. Therefore, the original decimal number could have been 23.65 if rounded to 23.7.
