The term "equal number" typically refers to two or more numbers being the same or having the same value. In this context, the number 80 itself is not equal or unequal; it simply represents a specific value. To determine if it is equal to another number, you would need to compare it to that other number. For example, 80 is equal to 80 but not equal to 70 or 90.
let x = decrease 80- 80 x = 70 80(1-x) = 70 1-x =70/80 x = 1-70/80 = 0.125 = 12.5%
nine-tenths (9/10) equals 90%
