Lets do this step by step:

  • 1 wall = 1 whole or [tex]\frac{1}{1}[/tex]
  • Jacob painted [tex]\frac{3}{4}[/tex] of the wall
  • [tex]\frac{1}{1} - \frac{3}{4} = \frac{1}{4}[/tex] (because [tex]\frac{3}{4}[/tex] is a quarter of 1 whole)
  • His little brother painted [tex]\frac{1}{2}[/tex] of the wall
  • [tex]\frac{1}{4}-\frac{1}{2} =[/tex]
  • Find the common denominator which is 4:
  • 1/4 × 1 = 1/4 and 1/2 × 2 = 2/4
  • [tex]= \frac{1}{2}[/tex] (because a half of 1/4 is 1/2)

Therefore your answer is "1/2."

Hope this helps!
