$\frac{3}{4}$ acres of seedling

Work Step by Step

The forester planted $\frac{5}{12}+\frac{11}{12}=\frac{5+11}{12}=\frac{16}{12}$ acres of seedlings. To calculate how many acres of seedlings remain, we can take the difference between the total amount of acres of seedlings planted and the amount of seedlings destroyed by frost. $\frac{16}{12}-\frac{7}{12}=\frac{16-7}{12}=\frac{9}{12}=\frac{9\div3}{12\div3}=\frac{3}{4}$ acres of seedlings.
