Answer 1

A. 3:2

B. Yes

C. 75%

Explanation:

A. Let's say Tracy had 10 problems on her test. This means she spelled 6 correctly and 4 incorrectly. Therefore the ratio is

6:4 which can be simplified into 3:2

B. Since Luis spelled less words incorrect, he did better than Tracy.

C. First we add 3 and 1 to get the amount of questions...

3+1=4

Then we find the percentage

3:4=3/4=75%
