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 2nd answer

123 rounded to the nearest 7 = 126
