The calculation method is as follows:
First multiply the dividend and divisor by 10 at the same time, turn the divisor into an integer, and then do vertical calculation. The vertical calculation is as follows:
48. 14÷8.3=48 1.4÷83=5.8
Extended data:
Division is one of the four operations.
It is more convenient to divide the divisor into integers first and then do vertical calculation.
Four operations refer to four operations: addition, subtraction, multiplication and division. Four operations are the important content of primary school mathematics and the basis of learning other related knowledge.
Addition: the operation of combining two numbers into one number.
Subtraction: the operation of finding the other Jm number when the sum of two addends is known.
Multiplication: the operation of finding the product of two numbers.
1, a number multiplied by an integer, is a simple operation to find the sum of several identical addends.
2. Multiplying a number by a decimal is to find a few tenths, a few percent and a few thousandths of this number.
3. A number multiplied by a fraction is a fraction of this number.
Division: the operation of finding another factor by knowing the product of two factors and one of them.
Multiplication is a simple operation of addition and division is a simple operation of subtraction.
Subtraction and addition are reciprocal operations, and division and multiplication are reciprocal operations.
Appendix+Appendix = Sum
Negative-negative = difference
One addend = and-the other addend.
Subtraction = minuend-difference
Subtraction = difference+subtraction
Factor × factor = product
One factor = product ÷ another factor
Dividend = quotient
Divider = Divider
Dividend = quotient × divisor
Vertical type means that each transition number is changed by the last transition number, and then the single digits of the last transition number are multiplied by 2. If carry is needed, proceed to 1, then increase the unit number by ten digits, and so on, and add a new operand to the unit number.
Longitudinal formula refers to a longitudinal formula in the calculation process, which makes the calculation simple.
