Answer 1

Răspuns:

sper ca te am ajutat!

Explicație pas cu pas:

1.

$\frac{7}{10} - \frac{2}{10} = \frac{5}{10}$

2.

$\frac{2}{4} + \frac{2}{4} = \frac{4}{4}$

3.

$\frac{3}{10} + \frac{6}{10} - \frac{7}{10} = \frac{2}{10}$

4.

$\frac{9}{10} - \frac{5}{10} = \frac{7}{10} - \frac{3}{10}$

5.

$\frac{4}{9} + \frac{3}{9} = \frac{7}{9}$

6.

$\frac{5}{3} - \frac{1}{3} = \frac{4}{3}$

7.

$\frac{148}{100} - ( \frac{56}{100} + \frac{31}{100} ) = \frac{61}{100}$

8.

$\frac{4}{4} + \frac{3}{4} + \frac{2}{4} = \frac{10}{4} - \frac{1}{4}$
