Answer:
Kindly check explanation
Explanation:
Given the question :
a. Carmen says that the sum of 11.2 and 19 will be irrational because 11.2 is not a rational number.
b. ella says that the product of 5 and 9 is an irrational number.
Describe the error made :
A) The product of 11.2 and 10 will give a rational output because 11.2 is rational, 11.2 is equivalent to 112 / 10, which shows it can be expressed in the form q/r.
B) The product of 5 and 9 cannot be irrational as both numbers multiplied, that is 5 and 9 are integers and are hence rational, the output (5 × 9) = 45 is also an integer and hence rational.
