Question

(-7/8 - 7/6) × 2,4 подскажите ответ хочу провериться у самого получилось -0,7

Answer 1

$- \frac{7}{8} - \frac{7}{6} = - \frac{21}{24} - \frac{28}{24} = - \frac{49}{24}$
$2.4 \times ( - \frac{49}{24} ) = \frac{24}{10} \times ( - \frac{49}{24} ) = - \frac{49}{10} = - 4 \frac{9}{10}$

Answer 2

Let's solve the expression step by step to verify your answer:

(-7/8 - 7/6) × 2.4

Step 1: Find the common denominator for the fractions (-7/8 and -7/6).

The common denominator for 8 and 6 is 24.

Step 2: Convert the fractions to have a common denominator of 24:

(-7/8) = (-7/8) * (3/3) = (-21/24)

(-7/6) = (-7/6) * (4/4) = (-28/24)

Step 3: Now, the expression becomes:

((-21/24) - (-28/24)) * 2.4

Step 4: Simplify the expression inside the parentheses:

((-21/24) + (28/24)) * 2.4

Step 5: Combine the fractions inside the parentheses:

(7/24) * 2.4

Step 6: Multiply the fractions:

(7/24) * 2.4 = 0.7

So, the correct answer is 0.7, not -0.7. It seems there was a sign error in your calculation.
