Write the common fraction in the form of a decimal fraction and calculate: \(\(\frac{3}{10}\) + 0,45 = ? 2,7 - \(\frac{9}{10}\) = ? \(\frac{24}{100}\) + 1,3 = ? 5,08 + 5\(\frac{15}{100}\) = ?

Решение:

• \( \frac{3}{10} + 0,45 = 0,3 + 0,45 = 0,75 \)
• \( 2,7 - \frac{9}{10} = 2,7 - 0,9 = 1,8 \)
• \( \frac{24}{100} + 1,3 = 0,24 + 1,3 = 1,54 \)
• \( 5,08 + 5\frac{15}{100} = 5,08 + 5,15 = 10,23 \)

Ответ: 0,75; 1,8; 1,54; 10,23.
