Question

question 6 of 10
kent and jodi both found the sum of two 4-digit numbers, but their results
were not the same. if kent made an error of addition by one in the hundreds
column and jodis result was correct, what was the difference between the
larger result and the smaller result?

a. 10

b. 1000

c. 100

d. 1

Explanation:

Step1: Understand place value

In a 4 - digit number, the places are thousands, hundreds, tens, and ones. The value of the hundreds place is $100$ (since $1\times100 = 100$).

Step2: Analyze the error

Kent made an error of addition by one in the hundreds column. This means that the difference between Kent's result and Jodi's (correct) result comes from the error in the hundreds place. If Kent added 1 more (or less) in the hundreds place, the difference in their results is $1\times100=100$. So the difference between the larger result and the smaller result is 100.

Answer:

C. 100
