98.5 (not 98.6)

1,182 ÷ 12

= 98.5

1182 = 98*12 + 6

1182/12 = 98 + 6/12 ..... (not 98 + 6/10)

The answer should have been 98.5

When he did his division he probably got an answer of 98 with a remainder of 6 so incorrectly wrote 98.6.

If he was using long division, he should have brought down a zero to get 60. Dividing by 12 gives 5 which would go after the decimal point as 98.5. At that point, subtracting results in zero and he can stop the long division.

Or he might have written the remainder as a fraction, but it needed to go over the original divisor of 12.

98 6/12

That reduces to 98½ or 98.5.

Answer:

The correct answer is 98.5 so the student made a mistake at the end of the division just putting the remainder 6 after the decimal point rather than continuing the division correctly.

"as shown" - ummmm, nothing is "shown".

1. No calculation shown as you suggest.

2. The answer is 98.5; not 98.6.

The error is this kid doesn't know how to divide, or subtract, or read a calculator, maybe he has poor eye sight and can't see the number correctly, maybe his mind was thinking one thing, his hand another, if you know what i mean.

It's 98.5, not 98.6

Even if we were inclined to do your homework for you, how would you expect people to find an error in a calculation that you didn't show? Did you miss the words "as shown"? Did you miss the fact that there was a picture with this question?
