Question

Помогите решить пример : 11/30-3/25+1/20=

Answer 1

$\frac{11}{50}-\frac{3}{25}+\frac{1}{20}=\frac{22-12+5}{100}=\frac{15}{100}=\frac{3}{20}=0,15$

Answer 2

Пошаговое объяснение:

$\frac{11}{50} - \frac{3}{25} + \frac{1}{20} =\frac{11}{50}-\frac{6}{50}+\frac{1}{20} =\frac{11-6}{50}+\frac{1}{20} =\frac{5}{50}+\frac{1}{20} =\frac{1}{10}+\frac{1}{20} =\frac{2}{20}+\frac{1}{20} =\frac{2+1}{20} =\\ frac {3}{20}=0.15$
