20 of them
20 times if you're counting by ones.
The odds of rolling a single one on a 20-sided die is 1 in 20 (1/20). Since the rolls are independent events, the odds of rolling two ones on two 20-sided dice would be (1/20) * (1/20), which simplifies to 1 in 400 (1/400).

There are 20 because 20 times 1/4 = 5
10 / (1/2) = 10* (2/1) = 20
20 1 = 1/1 = 10/10, or 10 tenths. 2 x 1 = 2 x 10/10 = 20/10 = 20 tenths
18 tens = 18 x 10 = 180 20 ones = 20 x 1 = 20 In total you have 200 So there are 2 hundred.

200 in total. 1 to 99: 20; 100 to 199: 120; 200 to 299: 20; 300 to 399: 20; 400 to 500: 20. So total: 200.
7 tens and 20 ones is 7 × 10 + 20 × 1 = 70 + 20 = 90 (ninety).
2 ones i think.... 50, 10, 10 ,10, 10, 10 or 20, 20, 20, 20, 10, 10
