Question

РЕШИТЕ ПО ДЕЙСТВИЯМ ПЛИЗ (2 1/3-3 1/4)*(2 3/4-0,95)

Answer 1

$(2 \dfrac{1}{3} - 3 \dfrac{1}{4})\cdot (2 \dfrac{3}{4} - 0,95) = -\dfrac{33}{20} \\\\ 1) \; 2 \dfrac{1}{3} - 3 \dfrac{1}{4} = \dfrac{28}{12} - \dfrac{39}{12} = -\dfrac{11}{12} \\\\ 2) \; 2 \dfrac{3}{4} - 0,95 = 2 \dfrac{3}{4} - \dfrac{95}{100} = 1 \dfrac{175}{100} - \dfrac{95}{100} = 1 \dfrac{80}{100} \\\\ 3) \; -\dfrac{11}{12}\cdot 1 \dfrac{80}{100} = -\dfrac{11}{12}\cdot \dfrac{180}{100} = -\dfrac{11}{1}\cdot \dfrac{15}{100} = -\dfrac{11}{1}\cdot \dfrac{3}{20} = -\dfrac{33}{20}$
