Answer:
1/4 as fraction
0.25 as decimal
= 0.25
Explanation:
Factors of 24 starting at 1 are:
1 x 24 = 24
2 x 12 = 24
3 x 8 = 24
4 x 6 = 24
Then the pattern repeats in decreasing orders of products of numbers . 6 x 4, 8,x 3 etc which are duplicates of the ones shown above
Factors of 24 are:
1, 2, 3, 4, 6, 8, 12, 24
There are 8 factors
Out of the 8 factors, only two - 12 and 24 are two digit numbers
P(factor is a 2 digit number = # two-digit numbers/Total # factors
= 2/8
= 1/4
= 0.25
