Question

срочно!!!! срочно!!!!!!!!!!!!!!!!! Обчисліть модуль: |7/12| + |- 5/9|
|- 3 3/9| - |- 2 1/6|​

Answer 1

$|\frac{7}{12}|+|-\frac{5}{9}|= \frac{7}{12}+\frac{5}{9}=\frac{7*3}{12*3}+\frac{5*4}{9*4}=\frac{21}{36}+\frac{20}{36}=\frac{41}{36}=1\frac{5}{36}\\\\|-3\frac{3}{9}|-|-2\frac{1}{6}|=3\frac{1}{3}-2\frac{1}{6}=(3-2)+(\frac{1}{3}-\frac{1}{6})=1+(\frac{2}{6}-\frac{1}{6})=1+\frac{1}{6}=1\frac{1}{6}$
