Вычислите:
(7,4-3целых2/3) : 8 - 1 =

( $frac{37}{5}$ - $frac{11}{3}$ ) : 8 - 1

1) $frac{37}{5}$ - $frac{11}{3}$ = $frac{111-55}{15}$ = $frac{56}{15}$

2) $frac{56}{15}$ : 8 = $frac{56}{15}$ * $frac{1}{8}$ = $frac{7}{15}$

3) $frac{7}{15}$ - 1 = $frac{7}{15}$ - $frac{15}{15}$ = - $frac{8}{15}$

ОТВЕТ: - $frac{8}{15}$
