найдите сумму натуральных решений неравенства m/13<9/52

[tex]\frac{m}{13} \ \textless \ \frac{9}{52} \\ \\ \frac{m}{13} -\frac{9}{52} \ \textless \ 0 \\ \\ \frac{4m}{52} -\frac{9}{52} \ \textless \ 0 \\ \\ \frac{4m-9}{52} \ \textless \ 0[/tex]

[tex]4m-9\ \textless \ 0 \\ 4m-9=0 \\ 4m=9 \\ m= \frac{9}{4} =2.25[/tex]

m∈(-∞;2.25)
m = {1;2}
1+2=3
