Answer: 8/9
Step-by-step explanation:
0.8888888 = 8/9
1 5/8 - 3/8 = 1 1/4
Subtract the numerators because the common denominators are the same and leave the whole number to make 1 2/8. To simplify it you divide it by 2 because that's the highest number that can go into both numerator and denominator to make is 1 1/4.
3000 + 500 + 60 = 3560
