Question

Which of the following makes this a true equation?

[] + 1 1/4 = 4 1/2

2 1/2

2 3/4

3 1/4

3 1/2

Answer 1

3 1/4

Answer 2

Set the unknown to x giving you x + 1(1/4) = 4(1/2)
Then simplify: x + 1x1/4 = 4x1/2 => x+1/4 = 4/2
Then subtract 1/4 from both sides => x + 1/4 - 1/4 = 4/2 - 1/4
Then find a common denominator => x = 8/4 - 1/4
Then simplify => x = 7/4 //That't gives you the answer.
Proof: 7/4 + 1/4 = 4 1/2 => 8/4 = 4 1/2 => 8/4 = 4/2 => 2 = 2
