Answer 2

Пошаговое объяснение:

$\[\begin{gathered}8\frac{7}{{36}}-x=3\frac{7}{9}\hfill\\x=8\frac{7}{{36}}-3\frac{7}{9}\hfill\\x=8\frac{7}{{36}}-3\frac{{7*4}}{{9*4}}\hfill\\x=8\frac{7}{{36}}-3\frac{{28}}{{36}}\hfill\\x=7\frac{{43}}{{36}}-3\frac{{28}}{{36}}\hfill\\x=4\frac{{15}}{{36}}=\boxed{4\frac{5}{{12}}}\hfill\\\end{gathered}\]$

$\[\begin{gathered}(x-0.25)+3\frac{1}{{12}}=7\frac{1}{3}\hfill\\x-0.25=7\frac{1}{3}-3\frac{1}{{12}}\hfill\\x-0.25=7\frac{{1*4}}{{3*4}}-3\frac{1}{{12}}\hfill\\x-0.25=7\frac{4}{{12}}-3\frac{1}{{12}}\hfill\\x-0.25=4\frac{3}{{12}}\hfill\\x=4\frac{3}{{12}}+0.25\hfill\\x=4\frac{1}{4}+0.25\hfill\\x=4\frac{1}{4}+\frac{{25}}{{100}}\hfill\\x=4\frac{1}{4}+\frac{1}{4}\hfill\\x=4\frac{{1+1}}{4}\hfill\\x=4\frac{2}{4}\hfill\\\boxed{x=4\frac{1}{2}}\hfill\\\end{gathered}\]$
