Answer:

-60. 75 or -60 3/4

Step-by-step explanation:

1            1

___ + ____

4           2

Make them have a common denominator

(I multiplied by 2 because 2 x 2 = 4 which 4 is the denominator of 1/4)

   1            2            2         1           3

____ x  ____  = ____ + ____ =____= .75 ( divide 3/4 which is .75)

   2           2             4          4         4

-48 - 12 = -60

-60. 75 or -60 3/4

The new depth of the submarine would be -60 3/4.
You add the variable together, then make it negative since it is about depth. Then you can easily find the answer (48 1/4+12 1/2=60 3/4)
