Question

PLEASE help me. This is honestly super confusing and I would love it if someone answered it. Also, please explain your answer as well. Thank you :)

Answer 1

Check the picture below.

so the wall is 146 inches wide, half of that is 73 inches.

the painting is 30 and 1/2 inches wide, half that is 15 and 1/4 inches.

if we subtract half the width of the painting from half the wall's width, the center of the painting will match the center of the wall.

`73~~ - ~~15(1)/(4)\implies 73~~ - ~~\cfrac{61}{4}\implies \cfrac{292~~ - ~~61}{4}\implies \cfrac{231}{4}\implies 57(3)/(4)`
