Выразите десятичной дробью:
а) 27%, 46%, 79%;
б) 30%, 90%, 50%;
в) 3%, 9%, 5%.
27% = $\frac{27}{100} = 0,27$;
46% = $\frac{46}{100} = 0,46$;
79% = $\frac{79}{100} = 0,79$.
30% = $\frac{30}{100} = \frac{3}{10} = 0,3$;
90% = $\frac{90}{100} = \frac{9}{10} = 0,9$;
50% = $\frac{50}{100} = \frac{5}{10} = 0,5$.
3% = $\frac{3}{100} = 0,03$;
9% = $\frac{9}{100} = 0,09$;
5% = $\frac{5}{100} = 0,05$.
