x = 1/3 = 4/12
y = 11/12

The distance between x and y is 7/12.

If the distance from x to z is 3/4 of the distance from z to y, then the difference of 7/12 must be divided into two parts in the ratio 3:4. It should be clear that the two parts are 3/12 and 4/12.

So z is 3/12 to the right of 4/12, at 7/12.

The distance from z to y is then the distance from 7/12 to 11/12, which is 4/12 = 1/3.

ANSWER: 1/3

the distance from x to y is
d=11%2F12-1%2F3
d=7%2F12
let the distance from z to y+be d1
then the distance from x to z be %283%2F4%29d1
d=d1%2B%283%2F4%29d1
7%2F12=%287d1%29%2F4
%287%2F12%29%2A4=7d1
7%2F3=7d1
d1=%287%2F3%29%2F7
d1=1%2F3.....the distance from z to y
=> %283%2F4%29d1=%283%2F4%29%281%2F3%29=1%2F4.....the distance from x+to z
answer: the distance from z to y is 1%2F3
check:
d1%2B%283%2F4%29d1=d
1%2F3%2B1%2F4=7%2F12
%284%2B3%29%2F12=7%2F12
7%2F12=7%2F12
