Question

Вычисли значение уравнения​

Answer 1

$a) \frac{3}{20} + \frac{7}{25} = \frac{15 + 28}{100} = \frac{43}{100}$

$b) \frac{7}{9} - \frac{1}{4} = \frac{28 - 9}{36} = \frac{19}{36}$

$\frac{1}{3} \div \frac{1}{6} + \frac{1}{18} = \frac{1}{3} \times 6 + \frac{1}{18} = 2 + \frac{1}{18} = \frac{37}{18}$

$\frac{1}{3} - \frac{2}{9} + \frac{5}{6} = \frac{6 - 4 + 15}{18} = \frac{17}{18}$
