When Xiao Ming calculates the division with remainder, he wrongly writes the divisor 115 as 151, and the result quotient is 3 larger than the correct result, but the remainder is exactly the same______ ．
Because the quotient is increased by 3, the divisor (151-115) △ 3 = 36 △ 3 = 12 can be obtained 7. So the answer is: 115 △ 12 = 9 7．
When calculating division with remainder______ It's a lot better than that______ The number is large
When calculating the division with remainder, the divisor is larger than the remainder
What is the divisor equal to in division with remainder
13639935943,
In division with remainder, divisor = divisor × quotient + remainder
Calculation: 53.3 ﹣ 0.23 ﹣ 0.91 × 16.1 ﹣ 0.82=
53.3 ／ 0.23 ／ 0.91 × 16.1 ／ 0.82 = 53.3 ／ 0.82 × (16.1 ／ 0.23) ／ 0.91, = 65 × 70 ／ 0.91, = 13 × 5 × 10 × 7 ／ 0.7 ／ 1.3, = 10 × 5 × 10 × 10, = 5000

Move the decimal point of a decimal one place to the right to get a new decimal. The sum of the two decimals is 16.94. What is the original decimal?
Let me tell you the method. Let X be 10x + x = 16.94, because one decimal point backward is equal to multiplying by 10
That's 16.94 divided by 11. 1.54
