1. Вычислите: 1) \(\frac{4,8}{1,44}\); 2) \(\frac{5,25}{2,5}\); 4) \(\frac{11}{18}\); 5) \(\frac{7}{4}\); 6) \(\frac{15}{4}\)

1) \(\frac{4,8}{1,44}\) = \(\frac{480}{144}\) = \(\frac{48 \times 10}{48 \times 3}\) = \(\frac{10}{3}\) = 3\(\frac{1}{3}\) 2) \(\frac{5,25}{2,5}\) = \(\frac{525}{250}\) = \(\frac{25 \times 21}{25 \times 10}\) = \(\frac{21}{10}\) = 2,1 4) \(\frac{11}{18}\) = 0,6111... 5) \(\frac{7}{4}\) = 1,75 6) \(\frac{15}{4}\) = 3,75 Ответ: 1) 3\(\frac{1}{3}\); 2) 2,1; 4) 0,6111...; 5) 1,75; 6) 3,75
