Expression: $8(p+7)-4+2 p$

Meena's work:
$\begin{array}{l}
8(3+7)-4+2(3) \\
8(10)-4+2(3) \\
80-4+6 \\
80-10 \\
70
\end{array}$

There is an error in Meena's work. Explain the error and correct it.

2/3 - 6/3 = -4/3 or -1 1/3 (negative one and one third)

0/0 because two thirds are lower then sixth rids unless u switch it then it would be 3/1

The result of two-thirds minus six-thirds is negative four-thirds, represented as − 3 4 ​ . When subtracting fractions with the same denominator, we can simply subtract the numerators. Therefore, the final answer is − 3 4 ​ .
