Question

(2 supra 3+5supra3)• 3 supra4-2 supra8:5supra16 ​

Answer 1

Răspuns:

Explicație pas cu pas:

2/3 + 5/3 = 7/3

7/3*3/4 = 7/4

2/8 : 5/16 = 2/8*16/5 = 4/5

7/4 - 4/5 = 35/20 - 16/20 = 19/20

Answer 2

$(\frac{2}{3}+\frac{5}{3})*\frac{3}{4}- \frac{2}{8}:\frac{5}{16}=$

$\frac{2+5}{3}*\frac{3}{4}- \frac{2}{8}*\frac{16}{5}=$

$\frac{7}{3}*\frac{3}{4}- \frac{4}{5}=$

$\frac{7}{4} -\frac{4}{5}=$

$\frac{35}{20} -\frac{16}{20}=$

$=\frac{19}{20}$
