Answer 2

Answer:

x:z = 5:3

Step-by-step explanation:

x     7                                 y       15

--- = ---   → 1               ;        ---  = ----     → 2

y     9                                  z       7

Multiplying 1 and 2, we get:

x     y     7     15

--- × --- = --- × ----

y      z     9      7

    x     15        5

∴ ---- = ----- =  ----

    z       9        3

∴ x:z = 5:3
