Question

alguém sabe essa conta (4/3x5/16+7/4

Answer 1

$\frac{4}{3}* \frac{5}{16} + \frac{7}{4} \\\\= \frac{4*5}{3*16} + \frac{7}{4} \\\\= \frac{20}{48}+ \frac{7}{4} \\\\ = \frac{20:4}{48:4}+ \frac{7}{4} \\\\ = \frac{5}{12}+ \frac{7}{4}\\\\= \frac{5*4 + 7*12}{12*4} \\\\= \frac{20+84}{48} \\\\= \frac{104}{48}\\\\= \frac{104:8}{48:8}= \frac{13}{6}$
