Jalen tries to find the difference: 1 - 2 He makes an error. Highlight Jalen's first error, 1 9 13

the given expression is
[tex]1\frac{2}{3}-\frac{7}{9}[/tex]the calculation is given as follows,
[tex]\begin{gathered} \frac{5}{3}-\frac{7}{9}=\frac{10-7}{9}=\frac{1}{3} \\ \end{gathered}[/tex]first we jump from 7/9 to 1
so the length will be
= 1 - 7/ 9
= (9-7)/9
= 2/9
now we have 2/9
then we jump from 1 to 1 2/3 or 1 to 5/3
so ,
[tex]\begin{gathered} 1\frac{2}{3}-1 \\ \frac{5}{3}-1 \\ \frac{5-3}{3}=\frac{2}{3} \end{gathered}[/tex]now the total length is
2/9 + 2/3
[tex]\frac{2}{9}+\frac{2}{3}=\frac{2+6}{9}=\frac{8}{9}[/tex]it is clearly seen that at the place of 4/9 there will be 8/9
6/9 will be 8/9.
