Question

Farmer Brown can harvest 2 1/3 acres of corn in one day. how many days will it take him to harvest 10 1/2 of corn?

Answer 1

Divide, so 10 1/2 ÷ 2 1/3 = 21/2 ÷ 7/3 = 21/2 × 3/7 = 9/2. About 9-10 days

Answer 2

`4(1)/(2)` days

Explanation:

Farmer Brown can harvest corn
`2(1)/(3)` or
`((7)/(3))` acres in = 1 day

He can harvest 1 acre corn in =
`(1)/((7)/(3))` days

It will take the number of days to harvest
`10(1)/(2)` or
`((21)/(2))` acres of corn

=
`(1)/((7)/(3))` ×
`(21)/(2)`

=
`(3)/(7)` ×
`(21)/(2)`

=
`(9)/(2)`

=
`4(1)/(2)` days

It will take Farmer Brown
`4(1)/(2)` days to harvest
`10(1)/(2)` of corn
