6.2 Pre-unit diagnostic assessment (Illustrative Math)

The school orchestra sells snacks at their concerts to raise money. At the spring concert, they made

\frac{9}{8}

as much money as they made at their fall concert.

Did they make more money at the spring of the fall concert?

Explain how you know.

(Choice A)
The spring concert raised a fraction of the amount the fall concert raised. So, the fall concert must have raised more money.
(Choice B)
The spring concert made more than $1$ ‍ times the amount the fall concert made. Multiplying by a number greater than $1$ ‍ increases the amount, so the spring concert must have raised more money.
