Question

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

Answer 1

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