Question

пожалуйста помогите.

Answer 1

$7)11 \frac{5}{8} + 7 \frac{1}{6} = 11 \frac{15}{24} + 7 \frac{4}{24} = \\ 18 \frac{19}{24}$
$\frac{451}{24} \div \frac{41}{12} = \frac{451}{24} \times \frac{12}{41} = \\ \frac{11 }{2} = 5 \frac{1}{2} = 5.5$
$8)8 \frac{7}{12} - 2 \frac{5}{8} = 8 \frac{14}{24} - 2 \frac{15}{24 } = \\ 7 \frac{38}{24} - 2 \frac{15}{24} = 5 \frac{23}{24}$
[tex] \frac{143}{24} \div \frac{13}{6} = \frac{143}{24} \times \frac{6}{13} = \\ \frac{11}{4} = 2 \frac{3}{4}

Answer 2

Ответ:

5 1/2

2 3/4

Пошаговое объяснение:

11 5/8+7 1/6=11 15/24+7 4/24=18 19/24

18 19/24:3 5/12=451/24*12/41=11/2=5 1/2

------------------------------------------

8 7/12-2 5/8=8 14/24-2 15/24=7 38/24-2 15/24=5 23/24

5 23/24:2 1/6=143/24*6/13=11 4=2 3/4
