What is the reciprocal or multiplicative inverse of -13?
the reciprocal (aka multiplicative inverse) of a number is 1/number, so the reciprocal of -13 is -1/13 (I moved the negative from the 13 to the 1 as per convention, 1/-13 = -1/13). The reciprocal of any number is what you have to multiply that number by to yield 1. -13 * -1/13 = (-13*-1)/13 = 13/13 = 1

Find the number that is exactly halfway between 9 and 17?
Two methods ;- #1 Write down all the numbers, and select the middle number. Hence 9,10,11,12,**13,**14,15,16,17 The answer is '13' . You will notice that there are four terms to either side of '13'. # #2 Tale the mean, by adding the two given numbers and dividing by '2'. Hence ( 9 + 17) / 2 = 26/2 = 13 The same answer again. !!!!!

Put the numbers 1 through 13 in 13 circlesso that three circles on a straight line add up to 21?
First find the center number. Then find number for each end. The formula for center number is highest number plus 1 then divide by 2. The first group will start with 1 (lowest) and 13 (largest) The next group will be the lowest from previous group plus 1 and previous largest number minus 1. ie 1 + 1 = 2; 13 -1 = 12 The center is 7 ((13 + 1)/7 = 7). You now need to find two other numbers to add with center number so that total will be 21. The lowest number is 1 and largest is 13. The next group will be lowest number plus 1 and highest number minus 1. So the number will be 1 + 13 + 7 2 + 12 + 7 3 + 11 + 7 4 + 10 + 7 ... ... go on until all numbers are used.

What is the greatest common factor for 39 d 13?
To find the GCF of 13 and 39, you can list the factors of each number. The factors of 13 are 1, 13. The factors of 39 are 1, 3, 13, 39. 13 is the GCF of 13 and 39. 3 is a prime number has only two factors: 1 and 13. 13 will divide into 39 three times. Since 13 is a prime number that will divide into 39, it has to be the GCF of 13 and 39.
