Question

вычеслите 4 1/6 : 50/3-1

Answer 1

$4 \frac{1}{6} \div \frac{50}{3} - 1 = - 0.75$

$1) \: 4 \frac{1}{6} \div \frac{50}{3} = \frac{25}{6} \times \frac{3}{50} = \frac{25 \times 3}{6 \times 50} = \frac{1 \times 1}{2 \times 2} = \frac{1}{4} \\ \\ 2) \: \frac{1}{4} - 1 = \frac{1}{4} - \frac{1}{1} = \frac{1}{4} - \frac{1 \times 4}{1 \times 4} = \frac{1}{4} - \frac{4}{4} = - \frac{3}{4} = - 0.75$
