Question

Calculam 4/3+6/5*5/9+1/4:3/8. b) 7/2:21/6-7/8+9/10*5/6. c) 1/2*16/3-3/4:5/8-7/15 só o que vcs sabem por favor cálculos

Answer 1

bem simples.

$\frac{4}{3}+ \frac{6}{5}* \frac{5}{9} + \frac{1}{4}: \frac{3}{8}$

$\frac{38}{15}* \frac{5}{9}+ \frac{1}{4} : \frac{3}{8}$

$\frac{38}{27}+ \frac{1}{4}: \frac{3}{8}$

$\frac{1,42}{36}: \frac{3}{8}$

$\frac{11,36}{108}$


$\frac{7}{2} : \frac{21}{6} - \frac{7}{8}+ \frac{9}{10}* \frac{5}{6}$

$\frac{2}{1}- \frac{7}{8} + \frac{9}{10}* \frac{5}{6}$

$\frac{9}{8}+ \frac{9}{10}* \frac{5}{6}$

$\frac{81}{40}* \frac{5}{6}$

$\frac{80}{48}$


$\frac{1}{2}* \frac{16}{3}- \frac{3}{4}: \frac{5}{8}- \frac{7}{15}$

$\frac{8}{3} - \frac{3}{4}: \frac{5}{8}- \frac{7}{15}$

$\frac{23}{12}: \frac{5}{8}- \frac{7}{15}$

$\frac{184}{60}- \frac{7}{15}$

$\frac{149}{60}$
