Question

Antoine is moving to a new house. His new room will be 50% larger than his old room. What equivalent expressions can you use to represent the size of Antoine’s new room?

1. Let r represent the size of Antoine’s old room. What expression represents how much larger his new room is than his old room?
2. Draw a diagram to represent Antoine's new room.
3. What addition expression represents the size of Antoine’s new room? How can you write an equivalent expression?

Answer 1

r = old room size

new room = 50% larger

n= new room size = r +.5r = 1.5r

n = 1.5r

.5r = how much larger the new room is:

.5r = n - r
