1/x+1/y=1/z where x=12 and y,z positive integer how many possible value of y and z ? Choose the correct choice from the following answers
A) 4
B) 7
C) 12
D) 15
E) infinite
1/12 = 1/z - 1/y   y = 12 * z / ( 12 - z )   0 &lt; z &lt; 12   Only for z = 3 ,4 ,6 ,8 , 9 ,10 and 11 , y is intiger   Hence seven solutions   ANSWER:7
<result>B</result>
1/x+1/y=1/z where x=12 and y,z positive integer how many possible value of y and z ?
