Question

-15/17*7/-30 подробное решение

Answer 1

Короче, при умножение двух отрицательных чисел произведение будет положительным, поэтому число без минуса в ответе. А так просто сократили и умножили

Answer 2

To solve the expression (-15/17) * (7/-30), follow these steps:

Step 1: Perform the multiplication inside the parentheses. Step 2: Perform the division of the two results obtained in step 1.

Let's begin:

Step 1: Multiply inside the parentheses: (-15/17) * (7/-30) = (-15/17) * (-7/30)

To multiply fractions, multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator:

Numerator: -15 * -7 = 105 Denominator: 17 * 30 = 510

Step 2: Now, we have the result of the multiplication from step 1, and we need to simplify it by performing the division:

(-15/17) * (7/-30) = 105/510

To simplify the fraction, we can find the greatest common divisor (GCD) between the numerator and denominator and divide both by it:

GCD(105, 510) = 15

Divide both the numerator and denominator by 15:

Numerator: 105 ÷ 15 = 7 Denominator: 510 ÷ 15 = 34

So, the simplified fraction is 7/34.
