Final answer:
The equation equivalent to Three-fourths + m = -7/4 is m = -1 13/16.
Step-by-step explanation:
We can solve the equation Three-fourths + m = -7/4 by isolating the variable m. We can do this by subtracting Three-fourths from both sides of the equation. This gives us m = -7/4 - Three-fourths. Simplifying this expression, we get m = -28/16 - 3/4, which is equivalent to m = -29/16 or m = -1 13/16.
Therefore, the equation equivalent to Three-fourths + m = -7/4 is m = -1 13/16.
