Question

2) y-5 целых 3/4=-6 целых 5/8​

Answer 1

Ответ:

Пошаговое объяснение:

y-5¾=-6⅝

y=5¾-6⅝

y=5*6/8-6*5/8( 5 целых шесть восьмых минус шесть целых пять восьмых)

y=-7/8

Answer 2

To solve the equation $y - \frac{5}{4} = -6 \frac{5}{8}$, we need to find the value of $y$.

Let's start by converting the mixed numbers into improper fractions: $-6 \frac{5}{8} = -\left(6 + \frac{5}{8}\right) = -\left(\frac{6 \times 8}{8} + \frac{5}{8}\right) = -\left(\frac{48}{8} + \frac{5}{8}\right) = -\frac{53}{8}$

Now, we can rewrite the equation as: $y - \frac{5}{4} = -\frac{53}{8}$

To get rid of the fractions, we can multiply the entire equation by the least common multiple (LCM) of the denominators. In this case, the LCM of 4 and 8 is 8.

Multiplying both sides of the equation by 8, we have: $8 \cdot \left(y - \frac{5}{4}\right) = 8 \cdot \left(-\frac{53}{8}\right)$

Simplifying: $8y - 10 = -53$

Now, let's isolate $y$ by adding 10 to both sides: $8y = -53 + 10$ $8y = -43$

Finally, divide both sides by 8 to solve for $y$: $y = \frac{-43}{8}$

Therefore, the solution to the equation is $y = \frac{-43}{8}$, which is an improper fraction.
