What's tiger calculating? Divide by 2 / 3. By mistake, divide by sign to see one thirtieth of the result. What's the correct answer?
Suppose that the result of the preceding series of numbers is x, then there is:
X × 2 / 3 = 1 / 30, calculated x = 1 / 20, so the correct answer is: X △ 2 / 3 = 1 / 20 △ 2 / 3 = 3 / 40

- 2. What is the diameter of the molecule? How many molecules are equal to 1 nm? Molecules are made up of atoms. The radius of atoms is (0.3) * 10 minus 10 square. Some people say that the order of molecular diameter is 1 angstrom, 1 angstrom = 10 ^ - 10 meters, 1 nanometer = 10 ^ - 9 meters, so about 10 molecules are arranged in a straight line, and the length is about 1nm. But the diameter of atoms is equal to that of molecules. Is the molecule made up of only one atom?
