- а) 37% = \(\frac{37}{100}\) (не сокращается)
- 83% = \(\frac{83}{100}\) (не сокращается)
- 61% = \(\frac{61}{100}\) (не сокращается)
- б) 15% = \(\frac{15}{100}\) = \(\frac{3}{20}\)
- 50% = \(\frac{50}{100}\) = \(\frac{1}{2}\)
- 60% = \(\frac{60}{100}\) = \(\frac{3}{5}\)
- в) 49% = \(\frac{49}{100}\) (не сокращается)
- 40% = \(\frac{40}{100}\) = \(\frac{2}{5}\)
- 80% = \(\frac{80}{100}\) = \(\frac{4}{5}\)
