A farmer wants to use half his land to raise crops. He would like to plant equal areas of corn, beans, and wheat. How much of the farmers land will be used to plant corn

1/6

Step-by-step explanation:

The portion for farming is only half ie 1/2

Since this portion is equally divided for corn, beans, and wheat, these are three different crops.

We divide the portion given by 3

1/2÷3

To get the division, we change the division sign into multiplication sign and the divisior reciprocated hence

1/2÷3 is same as 1/2*1/3

1/2*1/3=1/6

Therefore, each crop occupies 1/6 of the farmers land.
