In calculating a decimal subtraction, Xiao Hua regards 8 on the tenth place of the subtracted as 3 and 1 on the hundredth place of the subtracted as 7. The wrong answer is different from the correct one______ .

In calculating a decimal subtraction, Xiao Hua regards 8 on the tenth place of the subtracted as 3 and 1 on the hundredth place of the subtracted as 7. The wrong answer is different from the correct one______ .


0.8-0.3 = 0.5; 0.07-0.01 = 0.06; 0.5 + 0.06 = 0.56



When calculating a subtraction formula, Xiao Hua regards the error of 8 on the tenth of a subtracted as 3 and the error of 1 on the hundredth of another subtracted as 7


8 on the decile of the subtracted is regarded as 3, and the difference is reduced by 0.8-0.3 = 0.5
The 1 on the subtracted percentile is regarded as 7, and the difference is reduced by 0.07-0.01 = 0.06
Therefore, the wrong answer is less than the correct answer by 0.5 + 0.06 = 0.56



When Xiao Hua calculates a subtraction formula, he takes an 8 error on the tenth digit of a subtracted as 3, and a 2 error on the hundredth digit of another addend as 7. The correct answer is ()


The error of 8 on the decile of the subtracted is regarded as 3
The result is 0.5 less
Another 2 on the minus percentile is a 7
0.05 more
The result is 0.05 less
Add it all up to 5.67
Right?
