Answer 1

Answer:

The new level is $3 \frac{5}{8}$ inches.

Step-by-step explanation:

Given: At the start of summer, Little Crater Lake is $1 \frac{1}{4}$ inches below normal. By the end of summer, it had decreased an additional $2 \frac{3}{8}$ inches.

To find: What is it's new level?

Solution:

We have,

At the start of summer, Little Crater Lake is $1 \frac{1}{4}$ inches below normal.

So, at the start of the summer, Little Crater Lake is $\frac{5}{4}$ inches below normal.

By the end of summer, it had decreased an additional $2 \frac{3}{8}$ inches.

So, by the end of summer, it had decreased an additional $\frac{19}{8}$ inches.

Now, the new level is $\frac{5}{4} +\frac{19}{8} =\frac{10+19}{8}=\frac{29}{8} =3 \frac{5}{8}$ inches.

Hence, the new level is $3 \frac{5}{8}$ inches.
