Question

pleaseeee
$( \frac{3}{5} - \frac{1}{2} ) + ( \frac{21}{2} + \frac{5}{3} )$

Answer 1

3/5 - 1/2 = (6 - 5)/10 = 1/10

21/2 + 5/3 = (63 + 10)/6 = 73/6

1/10 + 73/6 = 736/60 = 12,26

Answer 2

$( \frac{3}{5} - \frac{1}{2} ) + ( \frac{21}{2} + \frac{5}{3} ) \\ ( \frac{6 - 5}{10}) + ( \frac{63 + 10}{6} ) \\ \frac{1}{10} + \frac{73}{6}$

MMC 10-6

10 - 6 / 2
5 - 3 / 3
5 - 1 / 5
1 - 1
--------------
2 . 3 . 5 = 30


$\frac{3 + 365}{30} \\ \frac{368}{30}$
12,26
