Step-by-step explanation:

15:45=45:x

1:3=45:x

1/3=45/x

x=3×45

x=135

Answer 2

Since the number are in continued proportion as it can be observed. Since it is x:y:z

So, on breaking continued proportion we can write it as -

A:B:C=A:B::B:C

SO,

15:45:X=15:45::45:X

AND BY using the formula

Product of means =PRODUCT of extremes

A*C=B*B

15*45=45*x

X=45
