To find x:z, we need to find the ratio between x and z.
Given that x:y = 7:9, we can rewrite this as x/y = 7/9.
Similarly, given that y:z = 15:7, we can rewrite this as y/z = 15/7.
To find x:z, we can multiply the two ratios:
(x/y) * (y/z) = (7/9) * (15/7)
The y’s cancel out, leaving us with:
x/z = (7/9) * (15/7)
Simplifying this expression, we get:
x/z = 105/63
x/z = 5/3
Therefore, x:z = 5:3.
