Describe the error each student makes. 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.

Kindly check explanation

Step-by-step 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.

answer: sine

step-by-step explanation:

what i would say the best answer is a. 40.5
