17/27 - 13/27 = 4/27 or four twenty-sevenths. Expressed as a decimal, this is equal to 0.148 recurring (that is, 0.148148148...)
9/10 - 13/30 = 27/30 - 13/30 = 14/30 = 7/15
-10 minus 17 is -27
-2x -11y - 13
18/27 minus 44/81 is 10/81
2/9 minus 5/27 = 1/27
13 - 27 = -14
40 - 27 = 13
9/10 - 13/30 = 27/30 - 13/30 = 14/30 = 7/15
-10 minus 17 is -27
27. 2+7=9 then minus 4. Next is plus 8 minus 3. Plus 9 minus 2. Plus 10 (27). Next is minus 1 which would be 26.
-2x -11y - 13
18/27 minus 44/81 is 10/81
2/9 minus 5/27 = 1/27
The median of the numbers 10 12 13 17 17 18 27 is 17.
43 minus 27 3/7 = 15 4/7
51 minus 27 3/7 = 23 4/7
First of all rearrange the numbers in Rank order. Hence 17,13,12,18,17,10,27 becomes. 10,12,13,17,17,18,27 The MEDIAN is the absolute middle term. Which is '17'. The MODE is the term which occurs most frequently. 17 appears twice, all the rest only appear once. Hence '17' is the mode. The MEAN is the sum of all the te rms divided by the number of terms. [10+12+13+17+17+18+27] / 7 = 114/7 = 16 2/7 = 16.2857 (4 dp_ is the Mean The RANGE is the difference between the greatest ad least terms. 27 - 19 = 17 is the Range.
