solmaris [256]

Answer:

-9\dfrac{5}{8} inches.

Step-by-step explanation:

The level of a lake was 8 inches below normal.

Now, it is given that the water level decreases 1\dfrac{1}{4} = 1.25 inches in June and 2\dfrac{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\dfrac{5}{8} inches. (Answer)

Sure! So you need to make an addition problem, for example, 200+25; that equals 225, right? Now you need to subtract from 225. For example, 225-10= 215. Hope I helped!
