• A. 13
• B. 14
• C. 13.5
• D. None of these

Answer 1

The correct option is B 14

Sam has 13 full chocolate bars and 0.7 of one chocolate bar $=13+0.7=13.7$

Estimating 13.7 to nearest natural number.

Step 1: Locate the number mentioned in the nearest place value (nearest natural number) i.e ones place

Step 2: Look at the digit to the right of the digit you want to estimate i.e 7 (tenths place)

Step 3: Follow the rule: If you see a digit nearest to natural number greater than 5, round up. If it is less than 5, round down.

7 in tenths place is greater than 5 so we increase the digit in ones coloum by 1.
$13.7\to 14.7$
Finally we eliminate the digits after rounded off digits.
Hence 13.7 estimated to nearest natural number is 14.
