Question

Is this sum rational or irrational? Explain.

Answer 1

Answer:

First answer:

"The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational."

Step-by-step explanation:

Both 1.12 and 18/7 are rational numbers (meaning that they can be written as a quotient of integer numbers:

1.12 = 112/100

Then, since the addition of rational numbers is also a rational number, their sum is another rational number.

Then the correct answer is:

The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational.
