It is: 47+52+63+66 = 228/4 => 57 which is the average mean
The answer is 63.LCM of 63 and 66 is 1386.GCF of 63 and 66 is 3. Given one number A, the formula for finding B, the unknown number, is : (LCM/A) x GCF = B (1386/66) x 3 = 21 x 3 = 63
fifty-four 47 + 21 + 34 + 50 = 152 65 + 78 + 66 + 71 = 280 152 + 280 = 432 as there are 8 numbers divide 432 / 8 = 54
180 -51 -63 = 66 degrees
50, 51, 52, 54, 55, 56, 57, 59, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76

-52 - 3 + 63 -52 + 66 + 14
(21 + 45) / (63 - 52) = 66 / 11 = 6

Rearrange the terms into their rank order. Already done!!! 63,65,66,75 For an EVEN number of terms; there are four terms here, and four is an even number. You take the middle two terms, which are ,65, & 66. and find the mid-point between them, Which is 65.5 Hence ' 65.5 ' is the MEDIAN term. NB If you have an ODD number of terms, 5 in this case, e,g, 63,65,66,66,75. Then you select the absolute middle term, which is ' 66 '.

percentage = 71.21%% rate:= 47/66 * 100%= 0.7121 * 100%= 71.21%
3 x 63 = 189 3 + 63 = 66
(-19+66)=(66-19)=47
The greatest common factor is of 66 and 47 is 1
