Round 123 to the nearest 7
Rounding means approximating
Find our target digit
Find our 2 possible answers:
Multiplying
7 by 17 gives us 119
Multiplying
7 by 18 gives us 126
Therefore, our answer is either 119 or 126
Determine the difference between our number 123 and 2 possible answers:
The difference between our first possible answer is:
123 - 119 = 4
The difference between our second possible answer is: 126 -
123 = 3
Since the smallest of these two numbers is 3, we use our 2
nd answer
123 rounded to the nearest
7 = 126
126
