Question

-18/15:(-6/70) ("/" означает дробь)

Answer 1

$- \frac{18}{15} \div ( - \frac{6}{70}) = - \frac{18}{15} \times ( - \frac{70}{6} ) = - \frac{3}{3} \times ( - \frac{14}{1} ) = - 1 \times ( - 14) = 14$

Ответ: 14.

Answer 2

To solve the given expression $-\frac{18}{15} : \left(-\frac{6}{70}\right)$, you can follow these steps:

1. Invert the divisor: When dividing fractions, you can multiply by the reciprocal of the divisor. The reciprocal of $-\frac{6}{70}$ is $-\frac{70}{6}$.

   So, the expression becomes $-\frac{18}{15} \times \left(-\frac{70}{6}\right)$.

2. Simplify the fractions: First, simplify the fractions individually.

   $-\frac{18}{15} = -\frac{6}{5}$ (both numerator and denominator can be divided by 3).

   $-\frac{70}{6} = -\frac{35}{3}$ (both numerator and denominator can be divided by 2).

3. Multiply the fractions: Multiply the simplified fractions together.

   $-\frac{6}{5} \times -\frac{35}{3} = \frac{6 \times 35}{5 \times 3} = \frac{210}{15} = 14.$

So, $-\frac{18}{15} : \left(-\frac{6}{70}\right) = 14$.
