Answer:
To find out what should be subtracted from -5/4 to get -1, we need to solve the equation if you dont know something in math you can always put it as x first.
-5/4 - x = -1
where x is the number that needs to be subtracted.
To solve for x, we have to simplify the left side of the equation:
-5/4 - x = -1
-5/4 + 4/4 - x = -1 (adding 4/4 to both sides)
-1/4 - x = -1
Now, we can isolate x by adding 1/4 to both sides of the equation:
-1/4 - x = -1
-1/4 + 1/4 - x = -1 + 1/4 (adding 1/4 to both sides)
-x = -3/4
Finally, we can solve for x by multiplying both sides by -1:
-x = -3/4
x = 3/4
Therefore, the number that should be subtracted from -5/4 to get -1 is 3/4.
