Arithmetic problem, suddenly I can't do it. I'm sorry, but I'm not sure if I can do it.

Calculate 40÷55 according to the question

Solution ideas: application of the key word for the average is generally used in division, the use of multiples is generally used in multiplication, more than who or less than who is generally used in addition and subtraction, according to the key word for the application of the formula

Solution process:

40÷55=0.727 remainder 0.015

Answer:A flower is equal to about 0.73 yuan

If you ask how many flowers there are in a dollar, then it is 55 ÷ 40

Extended information-Calculation process:Divide the divisor from the high digit of each digit of the divisor, each time you get the quotient of the quotient is retained, the remainder of the remainder plus the next digit of the operation, and so on the order of the divisor to complete the operation of the number of digits, and the quotient of the quotient of the sequential combinations, the last operation is the result of the remainder, the remainder is the result of the last operation. The remainder is the result of the last operation

Solution process:

Step 1: 400 ÷ 55 = 7 Remainder: 15

Step 2: 150 ÷ 55 = 2 Remainder: 40

Step 3: 400 ÷ 55 = 7 Remainder: 15

According to the above calculation, the result of the combination of the above steps is 727, the remainder of 15, because the divisor is enlarged by 1000 times. The divisor is enlarged by 1000 times, so the quotient is 0.727 and the remainder is 0.015

Calculation: 0.727×55+0.015=40
