Question

Farmer George is painting 3 33 chicken coops. He started painting this morning. Now he only has 1 3 4 1 4 3 ​ 1, start fraction, 3, divided by, 4, end fraction of a chicken coop left to paint this afternoon. How many chicken coops did Farmer George paint this morning?

Answer 1

Farmer George has painted
`(5)/(4)` OR
`1(1)/(4)` this morning.

Explanation:

Number of Chicken coops to be painted = 3

Amount of painting left =
`1(3)/(4)`

`1(3)/(4)` can Rewritten as
`(7)/(4)`

Amount of painting left =
`(7)/(4)`

We need to find the amount of chicken coops painted,

Amount of chicken coops painted can be calculated by Subtracting Amount of painting left with Number of Chicken coops to be painted.

Amount of chicken coops painted =
`3 - (7)/(4)`

Taking LCM we get;

Amount of chicken coops painted =
`(3*4)/(4) - (7)/(4)=(12)/(4) - (7)/(4) = (12-7)/(4) = (5)/(4)`

`(5)/(4)` can be written in mixed fraction as
`1(1)/(4)`

Hence Farmer George has painted
`(5)/(4)` OR
`1(1)/(4)` this morning.
