What are the formulas for quantity relations What are the commonly used quantity relations?

Too much, you ask which one.

Working hours * work efficiency = total amount of work.

Total work efficiency = working hours.

Total amount of work worked hours = work efficiency.

Speed Time = Distance.

Distance Speed = Time.

Distance Time = Speed.

Principal * Interest Rate Interest.

Unit price * quantity Total price.

Ergonomics* Time Total amount of work.

Unit Yield*Quantity Total Yield.

Number of copies per serving * number of copies Total speed = time * distance.

Principal * Interest Rate * Time Interest.

The main quantitative relations in the tree planting problem are: the number of intervals, the number of meters in each interval, the total number of meters;

The main quantitative relationship of sawing wood is: the number of saws, the time it takes to saw once, and the total time required;

The quantity relationship in the stair climbing problem is: the number of steps of the stairs, the number of steps of the stairs between two floors, and the number of segments of the stairs.

The main relationship of the bell ringing problem is: the number of times to wait, the time spent waiting once, the survival rate of the common time = the number of live trees, and the total number of trees.

Pass rate = total number of passes.

The quantity is equal to the total price divided by the unit price. Then you can see through this equation that the total price is the product of the quantity and the price of a single hail, and if you want to know the unit price, you can easily solve it by dividing the total price by the number of items purchased. Source year.

That is: total price = unit price * quantity, unit price = total price quantity, quantity = total price unit price.

For example: Xiao Ming spent a total of 200 yuan to buy books and shout oranges, and the ** of each book is 20 yuan, then, the number of books purchased by Xiao Ming = 200 20 = 10 (books).

Summary. Hello dear, the commonly used quantitative relations are as follows:

1. Divisor Divisor Quotient; Dividend quotient divisor; The quotient divisor is the dividend.

2. Factor factor product; The product of one factor is another factor.

3. The subtracted number is subtracted from the difference; Minused Difference Minus; The difference subtracted by the subtracted number.

4. Unit price, quantity, total price; Total price, unit price, quantity; Total price, quantity, unit price.

5. Work efficiency, working hours, total work; Total work efficiency = working hours. Total amount of work worked hours = work efficiency.

6, the number of additions, the number of additions, and; and one plus and the other plus.

Xiao Jun has 30 pictures, 12 less than Xiao Ming, how many pictures Xiao Ming has, and the number of pictures.

Hello Mr. Luo.

How to write a quantitative relation.

30 + 12 = 42 pieces, Xiao Ming has 42 pictures, the quantitative relationship formula: (42) one (30) = (12).

Thank you, Mr. Luo.
