Question

A submarine submerged at a depth of -48 1/4 meters dives an additional 12 1/2 meters. What is the new depth of the submarine?

Answer 1

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)

Answer 2

-60. 75 or -60 3/4

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
