Which statement is false?
A. No rational number is irrational.
B. Every irrational number is also real.
C. Every rational number is also an integer.
D. Every integer is also a rational number.

answer:

b.)Every real number is also rational

Step-by-step explanation:

This is false because all real numbers are irrational numbers!

no not all of them.

step-by-step explanation:

some of them have a square base.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
