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

Answer:

7/5

Step-by-step explanation:

Answer 2

Answer:

1$\frac{2}{5}$ of an acre or 1.4 acres.

Step-by-step explanation:

The least common multiple of 10 and 2 is 10.

Convert $\frac{9}{10}$ and $\frac{1}{2}$ to fractions with a denominator of 10.

$\frac{9}{10}$+$\frac{5}{10}$

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

$\frac{9+5}{10}$

Add 9 and 5 to get 14.

$\frac{14}{10}$

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

$\frac{7}{5}$= $1\frac{2}{5}$ =1.4

hope this helps!
