Rounding is when we make a number "simpler" but keep the value as close to the original number as possible. To round a number:
Determine which digit or place (value) is the number you want to "round to." All numbers after this (to the right) will become zeroes after rounding.
Keep it the same number if the next number (the number to its right) is less than 5. Then, change all other numbers to the right to 0. For example, 132 rounded to the nearest ten would be 130. (132 is closer to 130 than it is to 140.)
Increase the number by 1 if the next number (the number to its right) is 5 or more. Then, change all other numbers to the right to 0. For example, 158 rounded to the nearest hundred would be 200. (158 is closer to 200 than it is to 100.)
10.49 is the smallest answer choice, but 10.49 rounded to the nearest whole number is 10.
10.49 → 10
The next smallest answer choice is 10.5. 10.5 rounded to the nearest whole number is 11, making it the correct answer choice
10.5 → 11
