Answer: B. 38,273 + 51,425 = 89,798
Step-by-step explanation:
Let's check all the sum by adding their corresponding places.
A. [tex]46,371 + 32,618 = 78,989[/tex]
Its correct.
B. [tex]38,273 + 51,425 =89698\neq 89,798[/tex]
Here when we add the digits on the hundredth place we get 6 not 7.
Hence, it is the example of an error of addition by one.
Its correct.
C. [tex]13,246 + 84,631 = 97,877[/tex]
