Which of the statements below correctly compares the numbers 4⁄5 and 6⁄8.
4⁄5 = 6⁄8
4⁄5 > 6⁄8
4⁄5 < 6⁄8

The third option is correct because when you simplify 6/8 it is 3/4 and 3/4 is definetly bigger than 4/5.

First you have to make the fractions have like denominators to efficiently compare these fractions. 5 and 8 have a common denominator of 40, so you have to multiply top and bottom by 8 for 4/5 and by 5 for 6/8.
4/5 * 8/8 = 32/40
6/8 * 5/5 = 30/40
This shows that 4/5 is greater than 6/8. 4/5 > 6/8

If you are saving 20%, you are paying 80% because a percent is out of 100

100-20=80.
