Question

(-2+17\12):(3\8-1\6)-3ц1\4=

Answer 1

$( - 2 + \frac{17}{12} ) \div ( \frac{3}{8} - \frac{1}{6} ) - 3 \frac{1}{4} = - 6.05\\ \\ 1) \: - 2 + 1 \frac{5}{12} = - \frac{7}{12} \\ \\ 2) \: \frac{3}{8} - \frac{1}{6} = \frac{9}{24} - \frac{4}{24} = \frac{5}{24} \\ \\ 3) \: - \frac{7}{12} \div \frac{5}{24} = - \frac{7}{12} \times \frac{24}{5} = - \frac{14}{5} = - 2 \frac{4}{5} = - 2.8 \\ \\ 4) \: - 2.8 - 3.25 = - 6.05$

Ответ: -6.05

Answer 2

Let's solve the expression step by step:

1. Simplify the expression inside the parentheses: -2 + 17/12 = -2 + 1 5/12 = -2 + 1 + 5/12 = -1 + 5/12 = 4/12 + 5/12 = 9/12 = 3/4

   3/8 - 1/6 = (33)/(83) - (14)/(64) = 9/24 - 4/24 = 5/24

2. Now, divide the two results from step 1: (-2 + 17/12) / (3/8 - 1/6) = (3/4) / (5/24)

3. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: (3/4) / (5/24) = (3/4) * (24/5)

4. Cancel out common factors between the numerators and denominators: (3/4) * (24/5) = (3 * 6) / (4 * 1) = 18 / 4 = 9/2 = 4.5

5. Now, subtract 3 from the result obtained in step 4: 4.5 - 3 = 1.5

So, the final result of the expression is 1.5.
