Question

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

Answer 1

Lets do this step by step:

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

Therefore your answer is "1/2."

Hope this helps!
