Question

della bought a tree seedling that was 2 1/4 feet tall. during the first year, it grew 1 1/6 feet. after 2 years it was 5 feet tall. how much did the seedling grow during the 2nd year?

Answer 1

$2 \frac{1}{4} + 1 \frac{1}{6} =$ $3 \frac{5}{12}$-5=$1 \frac{7}{12}$
$1 \frac{7}{12}$ is the answer

Answer 2

If you would like to know how much did the seedling grow during the 2nd year, you can calculate this using the following steps:

during the first year: 2 1/4 feet + 1 1/6 feet = 9/4 + 7/6 = 27/12 + 14/12 = 41/12 = 3 5/12 feet

after two years: 5 feet - 3 5/12 feet = 5 - 41/12 = 60/12 - 41/12 = 19/12 = 1 7/12 feet

The seedling grew 1 7/12 feet during the 2nd year.
