Which of the following equations is true? 3+1 = 3.0 6.1:0 = 6 +1 +0 7:1 = 0 +7 O 1+1=1:1

We are asked to find out which of the given equation is true.
Let us analyze each of the given options
Option 1:
[tex]\begin{gathered} 3+1=3\cdot0_{} \\ 4\ne0 \end{gathered}[/tex]As you can see, the left and right side of the equation is not equal, therefore, this equation is not true.
Option 2:
[tex]\begin{gathered} 6\cdot1\cdot0=6+1+0 \\ 0\ne7 \end{gathered}[/tex]As you can see, the left and right side of the equation is not equal, therefore, this equation is not true.
Option 3:
[tex]\begin{gathered} 7\cdot1=0+7_{} \\ 7=7 \end{gathered}[/tex]As you can see, the left and right side of the equation is equal, therefore, this equation is true.
Option 4:
[tex]undefined[/tex]
