Total copies/number of copies = number of copies
Total copies/number of copies = number of copies
1 multiple × multiple = multiple
Multiply1Multiply = Multiply
Multiply/Multiply = 1 Multiply
Speed × time = distance
Distance/speed = time
Distance/time = speed
Unit price × quantity = total price
Total price/unit price = quantity
Total price ÷ quantity = unit price
Work efficiency × working hours = total workload.
Total amount of work ÷ work efficiency = working hours
Total workload ÷ working time = working efficiency
Appendix+Appendix = Sum
And-one addend = another addend
Negative-negative = difference
Negative difference = negative
Difference+Minus = Minus
Factor × factor = product
Product ÷ One factor = another factor
Dividend = quotient
Dividend = divisor
Calculation formula of quotient × division = division of primary school mathematical graphics
Square c perimeter s area a side length perimeter = side length× 4c = 4a area = side length× side length s = a× a.
Cube V volume A side length surface area = side length × side length× 6s table =a×a×6 volume = side length× side length v=a×a×a3 rectangle C circumference S area A side length circumference = (length+width )× 2C = 2 (a+b) area = length× width s=ab4 cuboid V volume S area A long volume = length.
Trapezoidal S area A upper bottom B lower bottom H height area = (upper bottom+lower bottom) × height ÷2s=(a+b)×h÷28 circular S area C perimeter ∏d= diameter r= radius (1) perimeter = diameter×∏ = 2×∏. Radius c=∏d=2∏r(2) area = radius× radius× 9 cylinder V volume H height S; Bottom area r bottom radius c bottom perimeter (1) lateral area = bottom perimeter × height (2) surface area = lateral area+bottom area× 2 (3) volume = bottom area× height (4) volume = lateral area ÷2× radius.
Cone v volume h height s; Base area r base radius volume = base area × height ÷3 total number ÷ total number = formula (sum+difference) ÷ 2 = large number (sum-difference) ÷ 2 = sum of decimal and multiple problems ÷ (multiple-1) = decimal × multiple = non-closed line of tree planting problem. Then the number of plants = number of nodes+1 = total length ÷ plant spacing-1 = total length × (number of plants-1) plant spacing = total length ÷ (number of plants -654438) then the number of plants = number of nodes = total length ÷. Then number of plants = number of segments-1 = total length ÷ plant spacing-1 total length = plant spacing × (number of plants+1) plant spacing = total length ÷ (number of plants+1) The quantitative relationship of tree planting problem on closed line is as follows: number of plants. The difference between the two distributions = the number of shares participating in the distribution (big loss-small loss) ÷ the difference between the two distributions = the number of shares participating in the distribution meets the problem; Meeting distance = speed × meeting time = meeting distance; The sum of speed and speed = meeting distance; Meeting time; Catch up with the problem; Distance = catch up with time; Distance; Speed difference = catching distance; Catch up with time; Downstream speed = ÷2 water flow speed = (downstream speed-countercurrent speed) ÷2 concentration problem Solute weight+solvent weight = solution weight Solute weight ÷ solution weight × 100% = concentration solution weight× concentration = solute weight Solute weight ÷ concentration = solution weight profit and discount problem profit = selling price-cost. × 100% increase or decrease = principal× increase or decrease percentage discount = actual selling price ÷ original selling price× 1 00% (discount <1) interest = principal× interest rate× time after tax interest = principal× interest rate× time × (1-)
