Question

Ella is testing out a new studying method and wants to know if it works. She decides to compare her spelling test scores from last week and this week. On last week's test, Ella spelled 16 out of the 20 words correctly. On this week's test, she spelled 13 out of the 15 words correctly. On which test did Ella get a higher ratio of correctly spelled words to total words?

Answer 1

The test where Ella got 13/15 has the higher ratio of correctly spelled words to total words.

Explanation:

On the last week's test, Ella got a 16/20, which equates to 80% correctly spelled words compared to total words. On this week's test, she got a 13/15, which equates to 86.6% correctly spelled words compared to total words. Since 86.6 > 80, the test where Ella got a 13/15 has the higher ratio.
