Question

пожалуйста 2 вариант срочно​

Answer 1

#1

$\frac{48}{84} = \frac{4}{7}$

$0.375 = \frac{375}{1000} = \frac{3}{8}$

$\frac{7 \times 12}{30 \times 21} = \frac{1 \times 2}{5 \times 3} = \frac{2}{15}$

#2

$\frac{6}{18} = \frac{3}{9} = \frac{1}{3} = \frac{12}{36}$

#3

а) В 1 сутках 24 часа:

$\frac{16}{24} = \frac{2}{3}$

б) В 1 километре 1000 метров:

$\frac{200}{1000} = \frac{1}{5}$

#4

$\frac{29}{x} = 1 \frac{1}{16} + 2 \frac{9}{16} \\ \frac{29}{x} = \frac{17}{16} + \frac{41}{16} \\ \frac{29}{x} = \frac{58}{16} \\ x = 8$
