Question

Scz daca nu se vede bn poza dar dau coroana ​

Answer 1

Explicație pas cu pas:

1. subunitare: 3/4, 5/6, 7/9

echiunitare: 7/7, 8/8

supraunitare: 9/7, 13/11

2.

$\frac{3}{1} + \frac{1}{2} - \frac{1}{8} = \frac{24}{8} + \frac{4}{8} - \frac{1}{8} = \frac{27}{8}$

$\frac{5}{6} + \frac{3}{5} = \frac{25}{30} + \frac{18}{30} = \frac{43}{30}$

$\frac{7}{8} \times \frac{16}{14} = \frac{112}{112} = 1$

$\frac{5}{6} \div \frac{10}{18} = \frac{5}{6} \times \frac{18}{10} = \frac{90}{60} = \frac{3}{2}$
