Answer: see below
Explanation:
To do this, we need to get the fractions to have a common denominator. The closest multiple of both 8 and 10 is 40. Whatever number gets both denominators to forty will need to be multiplied by both the numerator and the denominator
9/10 * 4/4 = 36/40
7/8 * 5/5 = 35/40
Now that both denominators are 40, we can compare the numerators to see which fraction is the largest. Since 36 is greater than 35, 9/10 > 7/8. I hope this helps!
