Question

A. Step 1 B. Step 2 C. Mario didn’t make a mistake

Answer 1

The answer is:

Step 2 (OPTION B)

SOLUTION

Problem Statement

The question gives us a solution of an expression and we are asked to find the mistake in the calculation.

Method

In order to solve this problem, we simply need to solve the question the right way and compare which step is correct

Implementation

The expression given is:

`(4)/(3)=q+(1)/(3)`

Simplifying this expression we have:

`\begin{gathered} \text{subtract }(1)/(3)\text{ from both sides} \\ (4)/(3)-(1)/(3)=q+(1)/(3)-(1)/(3) \end{gathered}`

The above expression is the same as Step 1.

Thus, Step 1 is correct.

Simplifying this expression further:

`\begin{gathered} (4)/(3)-(1)/(3)=q+(1)/(3)-(1)/(3) \\ (4-1)/(3)=q \\ \therefore(3)/(3)=q \end{gathered}`

This is the step that is different from Step 2.

Final Answer

The answer is:

Step 2 (OPTION B)
