My math is difficult to solve. For example, I want to stir 10 kg of noodles and put 4 kg of water. How many kg of water should I put in 28 kg of noodles?
Method 1: The amount of water added should be 4 ÷ 10 = 0.4 (kg) per kg of flour and 0.4× 28 = 1 1.2 (kg) for 28 kg of flour.
Method 2: 28 kg of flour is 28 ÷ 10 = 2.8 times of10, and the amount of water put is 2.8 times of 4 kg, 4× 2.8 = 1 1.2 (kg).
Method 3: The water is 4/ 10 = 2/5, 28× 2/5 = 1 1.2 (Jin) noodles.
