Question

5/6+2 3/10= 7 3/- 2 3/8=

Answer 1

Ответ:

$\frac{5}{6} +2 \frac{3}{10} = 10*\frac{5}{6} +6* \frac{23}{10} =\frac{50+138}{60} =\frac{188}{60} =\frac{94}{30} =\frac{47}{15}$=$3\frac{2}{15}$

$\frac{7}{3} -2 \frac{3}{8} =8*\frac{7}{3} -3*\frac{19}{8} =\frac{56-57}{24} =-\frac{1}{24}$

Пошаговое объяснение:

$\frac{5}{6} +2 \frac{3}{10} = 10*\frac{5}{6} +6* \frac{23}{10} =\frac{50+138}{60} =\frac{188}{60} =\frac{94}{30} =\frac{47}{15}$=$3\frac{2}{15}$

$\frac{7}{3} -2 \frac{3}{8} =8*\frac{7}{3} -3*\frac{19}{8} =\frac{56-57}{24} =-\frac{1}{24}$
