Answer:
sorry I don't get the question I am in MIDDLE school
Lets have 4x acres of soybeans , then it is going to be 9x acres of corn
(4x/9x=4/9)
Altogether we have (4x+9x) acres
Altogether he planted 400 acres
So, we can write
4x+9x=400
13x=400
x=400/13
4x acres of soybeans
4*400/13≈123 acres of soybeans
