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!
