Срочно

Answer 1

$\tt\displaystyle\frac{13}{50}+\frac{12}{50}+\frac{2}{50}=\frac{13+12+2}{50}=\frac{27}{50}$

$\tt\displaystyle\frac{56}{100}+\frac{15}{100}-\frac{9}{100}=\frac{56+15-9}{100}=\frac{62}{100}=\frac{31}{50}$

$\tt\displaystyle\frac{9}{25}+\frac{6}{25}+\frac{3}{25}=\frac{9+6+3}{25}=\frac{18}{25}$

$\bigg(\tt\displaystyle\frac{20}{45}+\frac{18}{45}\bigg)-\frac{29}{45}=\bigg(\frac{20+18}{45}\bigg)-\frac{29}{45}=\frac{38}{45}-\frac{29}{45}=\frac{38-29}{45}=\frac{9}{45}=\frac{1}{5}$
