On one test, Chi answered 76 out of 100 questions correctly . On another test , he answered 7 out of 10 questions corrctly. Write these scores as decimals and compare them.

I don't know..

76 out of 100 = 76/100 = 0.76

7 out of 10 = 7/10 = 0.70

To write the scores as decimals, simply divide the number of correct answers by the total number of questions for each test.

For the first test:
76 correct out of 100 total questions can be written as 76/100 = 0.76 as a decimal.

For the second test:
7 correct out of 10 total questions can be written as 7/10 = 0.7 as a decimal.

To compare the scores, we can see that 0.76 is greater than 0.7. So, Chi performed better on the first test than the second test.
