Question

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

Answer 1

$frac{m}{13} textless frac{9}{52} \ \ frac{m}{13} -frac{9}{52} textless 0 \ \ frac{4m}{52} -frac{9}{52} textless 0 \ \ frac{4m-9}{52} textless 0$

$4m-9 textless 0 \ 4m-9=0 \ 4m=9 \ m= frac{9}{4} =2.25$

m∈(-∞;2.25)
m = {1;2}
1+2=3
