Question

A farmer plowed 9/10 of a acre in the morning and 1/2 of an acre in the afternoon. How many acres did the farmer plow in all?

Answer 1

1
`(2)/(5)` of an acre or 1.4 acres.

Explanation:

The least common multiple of 10 and 2 is 10.

Convert
`(9)/(10)` and
`(1)/(2)` to fractions with a denominator of 10.

`(9)/(10)`+
`(5)/(10)`

Since these fractions now have the same denominator, add them by adding the numerators.

`(9+5)/(10)`

Add 9 and 5 to get 14.

`(14)/(10)`

Reduce the fraction to the lowest terms by extracting and canceling out 2.

`(7)/(5)`=
`1(2)/(5)` =1.4

hope this helps!
