Oblicz : 1) 10 - 2 x (3, 1/5 - 2, 1/4 x 1/3) = Proszę pomóżcie tylko to jedne , dam naj ;))

[latex]10-2cdot(3frac{1}{5}-2frac{1}{4}cdotfrac{1}{3})=10-2cdot(3frac{1}{5}-frac{ ot9^3}{4}cdotfrac{1}{ ot3_1})=10-2cdot(frac{16}{5}-frac{3}{4})\\=10-2cdot(frac{64}{20}-frac{15}{20})=10-2cdotfrac{49}{20}=10-frac{49}{10}=10-4,9=5,1[/latex] ©DRK
