400,000
If I am understanding your question correctly, the answer would be 10. One-fifth goes into 1 five times (five fifths equals one), and into 2 ten times.
it is 2 thousand
2.40 x 105 equals 240,000
They are the values of the different columns in the place value system we use. Each column is ten times bigger than the column to its right and ten times smaller than the column to its left. The whole (or units or ones) is ten times bigger than one tenth; The hundred is one hundred (or ten times ten) times bigger than one whole, making it one thousand (ten times ten times ten) bigger than one tenth.
It is: 10 times 1/5 = 2
One times ten to the negative fifth power
Two divided by one fifth is the same as two times five. The answer is ten (10)
2.5 times 10 to the fifth is 2,500,000
1.2 times ten to the fifth power in decimal notation is 120,000
The same thing as one fifth of any ten things - two.
