    Let number of telephones in the office be represented by "x"

    Number of telephones that have built in speaker phones = 1/4x

    Number of telephones that have built in conferencing capability = 1/2 * number of phones with built in speaker facility

    Number of telephones that have built in conferencing capability = 1/2*1/4x = 1/8x

    Number of telephones that have built in conferencing capability = 1/8x
