What number minus one half is equal to negative three fourths?

Answer 1

To find the number that, when decreased by one half, equals negative three fourths, we can set up the equation: ( x - \frac{1}{2} = -\frac{3}{4} ). Adding one half to both sides gives us ( x = -\frac{3}{4} + \frac{1}{2} ). Converting (\frac{1}{2}) to fourths gives (\frac{2}{4}), so the equation becomes ( x = -\frac{3}{4} + \frac{2}{4} = -\frac{1}{4} ). Thus, the number is (-\frac{1}{4}).
