21 and 20
5 because it is the only single digit number
There are 20 fifths in 4 wholes. This can be calculated by multiplying the number of wholes (4) by the number of parts each whole is divided into (5). So, 4 wholes x 5 parts = 20 fifths. Each whole can be divided into 5 equal parts, and since there are 4 wholes, there are a total of 20 fifths.
20/5 = 4, a whole number.
Both 10 and 20 are two-digit numbers that are factors of 20.
To find the number of 5-digit combinations from 1 to 20, we first calculate the total number of options for each digit position. Since the range is from 1 to 20, there are 20 options for the first digit, 20 options for the second digit, and so on. Therefore, the total number of 5-digit combinations is calculated by multiplying these options together: 20 x 20 x 20 x 20 x 20 = 3,200,000 combinations.
50% of numbers divisible by 5 are even, the other 50% are odd. If the single's digit of a number is 5, then the number is divisible by 5 and odd. For example, 25. However, if the single's digit of a number is 0, then the number is divisible by 5 and even. For example, 20.
A quintillion is a number with 18 zeros (19 digits). A 20-digit number would be 10's of a quintillion (20 digits since we add one more digit to the left).
2*10=20
100 quintillion is a 21 digit number with 20 zeroes.
20 and 2 fifths
In the number 28, the digit 2 holds a place value of 20, as it is in the tens place. This means that the value of the digit 2 is 20 times the place value, which is 2 x 10 = 20. Therefore, the value of the digit 2 in the number 28 is 20.
