20-29: zwanzig, einundzwangig, zweiundzwanzig, dreiundzwanzig, vierundzwanzig, fünfundzwanzig, sechsundzwanzig, siebenundzwanzig, achtundzwanzig, neunundzwanzig
30-39: dreizig, einunddreizig, zweiunddreizig, vierunddreizig, fünfunddreizig, sechsunddreizig, siebenunddreizig, achtunddreizig, neununddreizig
40: vierzig
From 20 to 100 counting in German follows the same pattern that you can see above.
I guess you mean: What number when you subtract 20, gives 40 as the answer?x - 20 = 40.Add 20 to both sides: x - 20 + 20 = 40 + 20x = 60
40
the percent of a number is when you multiply the percentage by the number, for example: 8% of 40 40 x 0.08= 20% or 20% of 40 0.20 x 40=8%
8 / 0.2 = 40 Therefore, the number that 8 is 20 percent of is 40.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
8 is 40% of 20
20 = zwanzig
8 / 0.4 = 20 Therefore, 8 is 40 percent of 20.
20 / 0.5 = 40 Therefore, 20 is 50 percent of 40.
These may help you answer your questions: 1, 2, 4, 5, 8, 10, 20 and 40.
