inches in June and 2
3
8
inches more in July. What was the new level with respect to the normal level?

Answer 1

`-9(5)/(8)` inches.

Explanation:

The level of a lake was 8 inches below normal.

Now, it is given that the water level decreases
`1(1)/(4) = 1.25` inches in June and
`2(3)/(8) =2.375` inches more in July.

Therefore, the new level of water with respect to the normal level will be

= - 8 - 1.25 - 2.375

= - 9.625 inches

=
`-9(5)/(8)` inches. (Answer)
