A farmer plant the same amount every day adding up to 1 2/3 acres at the end of the year. If the year is 2/5 over, how many acres has the farmer planted?

If the year is 2/5 over, then the farmer has already planted 2/5 * 1 2/3 acres = <<2/5*1 2/3=2/5*5/3=1/3>>1/3 acres.

The total number of acres the farmer has planted is 1 2/3 acres - 1/3 acres = 1 acres. Answer: \boxed{1}.

What's 1/2/ 3

To divide a fraction by a whole number, you can multiply the fraction by the reciprocal of the whole number. In this case, we want to divide 1/2 by 3, so we can multiply 1/2 by 1/3:

1/2 ÷ 3 = 1/2 × 1/3 = 1/6

Therefore, 1/2 ÷ 3 = 1/6.

Do you want to share one third of a box of jelly beans with your friends? How many groups of 1/9 of the box can you make out of the one third box?

To determine the number of groups of 1/9 of the box that can be made out of one third of the box, we need to find out how many times 1/9 can fit into 1/3.

To do this, we can multiply the fraction 1/3 by the reciprocal of 1/9:
1/3 ÷ 1/9 = 1/3 × 9/1 = 9/3

Simplifying the fraction 9/3, we get:
9/3 = 3

Therefore, you can make 3 groups of 1/9 of the box out of one third of the box.
