Part (a):
=========
The statement ⇒⇒⇒ 25 is to 75 as 50 is to 150
Can be written using fractions as following

25 : 75 = 50 : 150

∴
(25)/(75) = (50)/(150)
============================================

Part (b):
=========
The statement ⇒⇒⇒ 40 is to 90 as 8 is to 18
Can be written using fractions as following

40 : 90 = 8 : 18

∴
(40)/(90) = (8)/(18)
============================================
