The former is greater
The number with the greater coefficient and/or exponent is the greater number. n x 10^E where "n" is the coefficient, and "E" is the exponent. examples: 1.23 x 10^21 > 1.23 x 10^20 1.22 x 10^21 > 1.21 x 10^21 1.22 x 10^21 > 1.22 x 10^-21 see http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson25.htm for reference.
The new mean would be 7. The mean is the average of the data. (x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)/10=21 [(x1/3)+(x2/3)+(x3/3)+(x4/3)+(x5/3)+(x6/3)+(x7/3)+(x8/3)+(x9/3)+(x10/3)]/10=? [(1/3)(x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)]/10=? [(x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)/10]/3= 21/3=7
The prime numbers greater than 21 are 23, 29, 31, 37, 41, 43, 47, etc.
21/10 is already in simplest form as a fraction. As a mixed number it is 21/10

21 over 10 as a mixed number is 21/10
The first composite number greater than 21 is 22.

Nothing.. Because 21 is a Prime number
When comparing the values of two numbers, you can use a number line to determine which number is greater. The number on the right is always greater than the number on the left. In the example below, you can see that 14 is greater than 8 because 14 is to the right of 8 on the number line.
The number 21 in binary is 10101
The GCF is 3.
