Hi!
Irrational numbers cannot be whole numbers. In order to be a whole number, you cannot have any decimals or fractions. Irrational numbers possess these properties.
Hopefully, this helps! =)
True. For example, if 2 is a, and b was 0, then ab would automatically be 0. Both a and b can be 0 though, but at least one of them must be zero.
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75
The two fractions that added together give you a sum of -7/24 are 1/24+-8/24= -7/24
