Answer:
B. -19/25
Step-by-step explanation:
You are looking for an answer that is greater than -4/5 (which is equal to -0.80) but less than -3/4 (which is equal to -0.75). So, you can easily convert the fractions to decimals by dividing.
-33/50 = -0.66, which is greater than -0.75, so it can be eliminated.
-19/25 = -0.76, which fits our parameters, so it is the answer.
-19/20 = -0.95, which is less than -0.80, so it can be eliminated.
-7/10 = -0.70, which is greater than -0.75, so it can be eliminated.
