we are given:
#14/28# #=# #9/p#

Here, p is the unknown

Shifting p to the L.H.S (numerator)
we get:

#14/28# x p #=# 9

now, shifting #14/28# to the R.H.S:

p #=# 9 x #28/14#

on solving,
p #=# 18

So our proportion is :
#14/28# #=# #9 / 18#
note: on solving the fractions we get the equal value of 0.5 on both the sides
L.H.S = R.H.S hence they are in proportion.
