In our normal base 10 number system, each digit has a value ten times bigger than the digit to its right and ten times smaller than the digit to its left. The column before (left of) the decimal point is the units (or ones) column. The column to its left is ten times bigger than this at 1 × 10 = 10 - the tens column; the column to the left of the tens column is tens times bigger than this at 10 × 10 = 100 - the hundreds column, and so on. From the tens column, the column to its right is ten times smaller than this at 10 ÷ 10 = 1 - the units column; the column to the right of the units column (after the decimal point) is ten times smaller than this at 1 ÷ 10 = 1/10 = 0.1 - the tenths column; the column to its right is ten times smaller than this at 1/10 ÷ 10 = 1/100 = 0.01 - the hundredths column, and so on.
One column in a hundredths grid has 10/100's in it One column in a tenths grid has 1/10 in it. You can tell that 10/100=1/10 by looking at the two visuals.
At any given pressure and temperatire, a volume of air can hold a certain amout of water vapour before is begins to condense out (into water droplets). 10% humidity means that the amount of water vapour in the air is 10% of what the air could hold at that pressure and temperature.
You can replace any 10 counters in the 1000 column by 1 in the 10000 column. You can replace 10 counters in the 1000 column by 1 in the 100000 column. So the answer is yes.
