20 - zwanzig
Twenty in German is zwanzig (pronounced: tzvahn-tzik).The numbers remain the same.
(12/13)x = 20x = 20 / (12/13) = (20 x 13) / 12 = 21 and 2/3
4 (4*3=12, 4*5=20)
To find the mean of the numbers 20, 12, 20, 15, 8, 20, 12, and 10, first add them together: 20 + 12 + 20 + 15 + 8 + 20 + 12 + 10 = 117. Then, divide the total by the number of values, which is 8: 117 ÷ 8 = 14.625. Therefore, the mean is 14.625.
How about 6, 12 and 20?
12 and 20
The sum of two numbers between 20-40 is 58. The difference is 12
12 and 8
8 & 12
116
12 = 2x2x3 20 = 2x2x5 the both have 2x2 in common = 4
The composite numbers between 10 and 20 are 12, 14, 15, 16 and 18.
