Answer:
For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.
Step-by-step explanation:
There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.
