Fraction of chicken powder left after using

= 1 -
14 =
34 Amount of chicken powder left after using some = 3 u
Amount of chicken powder after buying 24 kg of chicken powder = 3 u + 24
3 u + 24 = 9 u
9 u - 3 u = 24
6 u = 24
1 u = 24 ÷ 6 = 4
Amount of chicken powder that Mrs Lee had at first
= 4 u
= 4 x 4
= 16 kg
Answer(s): 16 kg
