if the prime factorization of the denominator contains all 2's, all 5's, or a combination of 2's and 5's only, then the decimal expansion of the fraction will be terminating; also if the denominator is a power of ten to begin with, you don't have to factor, the decimal expansion will be terminating
Hi Mark, I know it is not the way a high school student would do the problem but I used to give this problem to my seventh graders when I was a teacher and I just wanted to point out that patterns exist throughout mathematics and if the student ever got stuck on a problem like this it would be nice to know about patterns and thus be able to solve the problem.

Mathematics professor at Community Colleges. 1/ 8 = 0.125 = 12.5 % / Same as converting 1/8 of a dollar to cents. first convert it to decimal number, then Multiply by 100 ( shift decimal point twice to the right) and insert %. ( divide by 100) .
Solutions: 1. P (X ≤ 4) Since we’re finding the probability that the random variable is less than or equal. to 4, we integrate the density function from the given lower limit (1) to the limit. we’re testing for (4). We need not concern ourselves with the 0 part of the density function as all it.
1st convert to decimal number 1/8 = 0.125. 2nd Multiply 0.125 by 100 ( shift decimal place twice to the right.) 0.125 * 100 = 12.5. 3rd divide 12.5 by 100 : insert % by 12.5 = 12.5 %. Upvote • 0 Downvote. Add comment.

For multiplication, use the *. symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also. be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2 (x + 5); 2x * (5) can be entered as 2x (5). The * is also optional when multiplying parentheses, example: (x + 1) (x – 1).
If there are 6 altimeters that are correctly calibrated and two that are not, then there are 8 in total. Since three altimeters are randomly selected, we can assume the probability of any 1 being selected is equal (i.e.1/8).
First for ease of data entry you could probably change your fraction to a decimal. That decimal is 0.875. cos-1 (0.875) = will give you an acute angle in degrees whose cosine is 0.875. cos-1 (0.875) = 28.95502437° Keep in mind the Quadrants when you are looking for angles between 0 and 180 degrees.
