Question

ЭТО СРОЧНО!!!
Дріб 7/12 - 3/8 =
2 11/16 - 1 5/8 =
3 6/35 + 3/10 =​

Answer 1

$\frac{7}{12} -\frac{3}{8} = \frac{14-9}{24} =\frac{5}{24}$

$2\frac{11}{16} -1\frac{5}{8} =(2-1)+(\frac{11}{16} -\frac{5}{8} )=1+\frac{1}{16}$

$3\frac{6}{35} +\frac{3}{10} =\frac{111}{35} +\frac{3}{10} =\frac{243}{70}$
