Помогите, прошу! Это срочно! УМОЛЯЮЮЮЮ!$1\frac{7}{8} * (12, 2 - 10 \frac{2}{3} ) : \frac{1}{4} + 16$

Answer 1

1 7/8 • (12,2 -10 2/3) : 1/4 + 16 =
= 15/8 • (122/10 - 32/2) : 1/4 + 16 =
= 15/8 • (122/10 - 160/10) : 1/4 + 16 =
= 15/8 • (-38/10) : 1/4 + 16 =
= -15•38•4/(8•10•1) + 16 =
= -15•19/10 + 16 =
= -285/10+16 =
= -28,5 + 16 = -12,5
