are the rational numbers a subset of all real numbers? are the rational numbers a subset of the irrational numbers? explain

Rational numbers are a subset of all real numbers while rational numbers are not a subset of irrational numbers.

Real numbers encompasses all rational and irrational numbers, integers, whole numbers and natural numbers with the exclusion of complex numbers usually written in the form 8+i, √-1.

Hence, real numbers include numbers such as 1/4, 0.444, 0, 1, - 4, √6 and so on.

Hence, rational numbers are a subset (a part) of all real numbers .

Rational numbers are not a subset of irrational numbers as they are complement (a rational number cannot be irrational and vice versa) of one another.

• Rational numbers are numbers which can be expressed in the form a/b where b ≠ 0. While ;

• Irrational numbers are numbers which o cannot be expressed in the format a/b. Irrational numbers include √6, 0.13412... e.t.c

Step-by-step explanation:

are the rational numbers a subset of all real numbers?

yes of course

by definition the real numbers is the union of the rational numbers and the irrational numbers

so we can say that the rational numbers are a subset

and every rational number is part of the real number

are the rational numbers a subset of the irrational numbers?

No

the rationals numbers are all those numbers that you can write as p/q with q different of 0, and the irrationals numbers are those that you cannot write as a fraction

so as you can see those are two completely different types of number, to be a subset every rational number must be in the irrationals , and by the definition we know it can't happen

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
