1/6 + 1/5 the common denominator is 30
= (1 x 5)/(6 x 5) + (1 x 6)/(5 x 6)
= 5/30 + 6/30
= (5 + 6)/30
= 11/30

4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
Suppose the number is x. Then x + 5/x = 6 Multiplying throughout by x, x2+5 = 6x or x2 - 6x + 5 = 0 which can be factorised into (x-1)*(x-5)=0 So x = 1 (and 5 times its reciprocal is 5) or x = 5 (and 5 times its reciprocal is 1).
1/6 because 121/11=11-5=6=6/1(reciprocal)=1/6
