Final answer:
To compare -3/5 and -7/8, find a common denominator. Rewrite the fractions with the common denominator and compare the numerators to determine which fraction is greater.
Step-by-step explanation:
To compare -3/5 and -7/8, we can find a common denominator. The least common multiple of 5 and 8 is 40. So, we can rewrite the fractions as -24/40 and -35/40. Now, we can compare the numerators. Since -24 is greater than -35, -3/5 is greater than -7/8.
