Fraction of chicken powder left after using
56 of it
= 1 -
56 =
16 Amount of chicken powder left after using some = 1 u
Amount of chicken powder after buying 22 kg of chicken powder = 1 u + 22
1 u + 22 = 12 u
12 u - 1 u = 22
11 u = 22
1 u = 22 ÷ 11 = 2
Amount of chicken powder that Mrs Chau had at first
= 6 u
= 6 x 2
= 12 kg
Answer(s): 12 kg
