Question

How can i write all the names that apply to -7/8, √0.15, √18/2, √45

Answer 1

The name that applies to all of the numbers given in the question is ‘real numbers’. Real numbers can be both rational — like the fraction -7/8 and the square root of 18/2 — and irrational numbers — like the square roots of 0.15 and 45.
