What can be represented as fractions, rational numbers, or irrational numbers?

1 answer:

3 0

Hmm question is a little confusing but fractions can be represented as division or a part of somthing, like 4 pieces of an 8 slice pizza, or you have 8 peices of pizza and you divide them by 4.

104 = 8y
