Answer: 58/9
Step-by-step explanation:
Unfortunately, Nicholas' steps in simplifying the fraction is not reflected in the question. However, the general idea of the simplifying fraction is to find the greatest common factor (GCF) of both the numerator and the denominator. In this case, the GCF is 10. Then, divide both numbers by the GCF. The answer for this item should be 2/3.
18. 0.625
19. -0.75
20. -4/10 = -0.4
The first is proportional the second is proportional and the third is not proportional
