Question

3/4*(-1/5)=-0,15и3/4(-4/5)= - 0,6​

Answer 1

Ответ:

Оба равенства верны

Пошаговое объяснение:

3/4*(-1/5)=-0,15

-3/20=-0,15

-0,15=-0,15 (верно)

3/4(-4/5)= - 0,6​

-3*1/5=-0,6

-3/5=-0.6

-0,6=-0,6 (верно)

Answer 2

Your calculations are not correct. Let's break down the calculations step by step:

1. $\frac{3}{4} \cdot \left(-\frac{1}{5}\right)$:

To multiply fractions, you simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together.

Numerator: $3 \cdot (-1) = -3$ Denominator: $4 \cdot 5 = 20$

So, $\frac{3}{4} \cdot \left(-\frac{1}{5}\right) = -\frac{3}{20}$, which is approximately -0.15, not -0.15 and 3/4.

2. $\frac{3}{4} \cdot \left(-\frac{4}{5}\right)$:

Again, multiply the numerators and denominators together.

Numerator: $3 \cdot (-4) = -12$ Denominator: $4 \cdot 5 = 20$

So, $\frac{3}{4} \cdot \left(-\frac{4}{5}\right) = -\frac{12}{20} = -\frac{3}{5}$, which is equal to -0.6, not -0.6 and 3/4.

So, the correct results are:

$\frac{3}{4} \cdot \left(-\frac{1}{5}\right) = -\frac{3}{20}$ (approximately -0.15)

$\frac{3}{4} \cdot \left(-\frac{4}{5}\right) = -\frac{3}{5}$ (equal to -0.6)
