Question

3/4+3/4*2/3+1/3 обчислить

Answer 1

$frac{3}{4} + frac{3}{4} * frac{2}{3} + frac{1}{3} =frac{15}{12}$
$frac {3}{4} * frac{2}{3} = frac{3*2}{4*3} = frac{6}{12} =frac{1}{6}$
$frac {3}{4}+frac{1}{6} = frac{9}{12} + frac{2}{12} = frac{11}{12}$
$frac{11}{12} + frac{1}{3} = frac{11}{12} + frac{4}{12} =frac{15}{12}$
