Hi ,
definition :
INVERSE PROPORTION :
----------------------------------
Two quantities x and y are said to vary in inverse proportion if
xy = k -----------( 1 )
where k is a constant.
according to our problem
y = 45 ,
k = 9 .
put these values in ( 1 ),
xy = k
x × 45 = 9
x = 9 / 45
x = 1/5
if y = 45 then x = 1/5
i hope this is useful to you.
