5)2 1/2+3=?​

Answer 1

Ответ:

1)

$3 \frac{7}{6} + 6= \frac{25}{6} + \frac{36}{6} = \frac{61}{6} = 1 \frac{1}{6}$

2)

$20 \frac{4}{7} - 20 = \frac{4}{7}$

3)

$18 - \frac{3}{4} = \frac{72}{4} - \frac{3}{4} = \frac{69}{4} = 17 \frac{1}{4} = 17.25$

4)

$19 \frac{2}{3} - 18 = \frac{2}{3}$

5)

$2 \frac{1}{2} + 3 = 5 \frac{1}{2} = 5.5$
