In August, due to the hot weather, the water consumption of Xiaojun's family increased by 20%.

(1) If 12 tons is increased every month now, the previous monthly water consumption will be:

12 ÷ (1+20%) =10 ton

(2) If the current monthly water fee is 56 yuan, the previous monthly water fee is:

56 present (1+20%) ≈ 46.67 yuan.
