The weight difference between the two barrels of oil is 9kg. If 15% of the weight of oil in barrel a is equal to 12% of the weight of oil in barrel B, then the weight of oil in barrel B is the same______ &Kg

The weight difference between the two barrels of oil is 9kg. If 15% of the weight of oil in barrel a is equal to 12% of the weight of oil in barrel B, then the weight of oil in barrel B is the same______ &Kg

According to the meaning of the question, the weight of a barrel of oil × 15 = the weight of B barrel of oil × 12, so the weight of a barrel of oil: the weight of B barrel of oil = 12:15 = 12 × 5 ﹥ 52 the weight of B barrel of oil: 9 ﹥ 2 (5-2) × 2 = 9 ﹥ 3 × 2 = 6 (kg), so the answer is: 6

There are two bottles of oil, bottle a and bottle B. their weight is equal. If 20% of the oil is poured out of bottle a to bottle B, then the oil in bottle a is equivalent to a fraction of the oil in bottle B

A is 0.8, B is 1.2, a is 2 / 3 of B

The weight ratio of a barrel to B barrel is 4:3. After a barrel pours 25 kg of oil into B barrel, the weight ratio of a barrel to B barrel is 1:2. How many kg of oil does a barrel and B barrel have
(there's also a formula. I really can't think of this problem.)
Equation!

The weight ratio of a barrel to B barrel is 4:3. After a barrel pours 25 kg of oil into B barrel, the weight ratio of a barrel to B barrel is 1:2. How many kg of oil does a barrel and B barrel have
Suppose a is 4x kg and B is 3x kg
（4x-25）：(3x+25)=1:2
x=15
So a = 15 × 4 = 60 kg
B = 3 × 15 = 45 kg

A and B two barrels of oil, the weight of a barrel of oil is three times that of B barrel of oil, if you take out 28 kg from a barrel, B barrel add 4 kg, then the weight of two barrels of oil is equal, a and B two barrels of oil how many kilograms of oil?

B barrel: (28 + 4) △ 3-1, = 32 △ 2, = 16 (kg), a: 16 × 3 = 48 (kg); a: there was 48 kg oil in a barrel and 16 kg oil in B barrel
