Any number not in the 13 times table. E.g 14, 15, 16,... but not 26.
14/26 = 7/13 = 0.538461538 = 53.85%
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
10/13 × 26/15 = 4/3 or 11/3
To find the mean, add the numbers (38 + 37 + 15 + 14 = 104) and divide by 4, resulting in a mean of 26. The median is the average of the two middle numbers when sorted (14, 15, 37, 38), which is (15 + 37) / 2 = 26. The mode is not applicable here since all numbers appear only once. The range is the difference between the highest and lowest values (38 - 14 = 24).
(13 + 15 + 26 + 11 + 26 + 16 + 12)/7 = 17 ====
Any number not in the 13 times table. E.g 14, 15, 16,... but not 26.
First put them in order:11, 12, 13, 15, 16, 26, 26.Then use your fingers the numbers at the opposite ends:11, 12, 13, 15, 16, 26, 26.Then keep moving in11, 12, 13, 15, 16, 26, 26.11, 12, 13, 15, 16, 26, 26.Until you come to the middle:11, 12, 13, 15, 16, 26, 26.So the median is 15.
14/26 = 7/13
14/26 simplified as 7/13.
14/26 = 7/13 = 0.538461538 = 53.85%
5/13 ÷ 15/26 = 2/3
13
30 over 26 in simplest form = 15/13
1, 2, 7, 14 1, 2, 13, 26
26/30 = 13/15
10/13 × 26/15 = 4/3 or 11/3
