Answer» Step-by-step explanation: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 |
