Jacob painted 3/4 of a wall his little brother painted 1/2 of what was left how much of the wall is still unpainted

Leni [432]

Lets do this step by step:

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