The addition and subtraction of mathematical fraction There are two barrels a and B. barrel a holds 6 and 1 / 3 more water than barrel B. if 2 and 1 / 4 water is taken out of barrel a and poured into barrel B, how much more water is in barrel a than barrel B? (step by step)

The addition and subtraction of mathematical fraction There are two barrels a and B. barrel a holds 6 and 1 / 3 more water than barrel B. if 2 and 1 / 4 water is taken out of barrel a and poured into barrel B, how much more water is in barrel a than barrel B? (step by step)


6 1 / 3 to 19 / 3 2 1 / 4 to 9 / 4
Let the water in bucket B have X, and that in bucket A has x + 19 / 3x = 22 / 3x
Solve the equation 22 / 3x-9 / 4x - (x + 9 / 4x)
It is 11 / 6x
There is 11 / 6 more water in bucket a than in bucket B
