Question

8 9/10 - x=4 5/6розв'язання ​

Answer 1

Ответ:

8 9/10-х=4 5/6

х=8 9/10-4 5/6(приводим к общему знаменателю.9/10 умножаем на 3,а 5/6 умножаем на 5)

х=8 27/30-4 25/30

х=4 2/30(сокращаем)=4 1/15

Answer 2

Пошаговое объяснение:

8 9/10 - х = 4 4/5

х = 8 9/10-4 4/5

х= 4 1/10

Answer 3

To solve the equation 8 9/10 - x = 4 5/6, we need to first convert the mixed numbers into improper fractions.

8 9/10 can be written as (8 × 10 + 9)/10 = 89/10. 4 5/6 can be written as (4 × 6 + 5)/6 = 29/6.

So the equation becomes: 89/10 - x = 29/6.

To eliminate the fractions, we can multiply both sides of the equation by the least common multiple (LCM) of the denominators, which in this case is 30.

(30 * 89/10) - (30 * x) = (30 * 29/6).

This simplifies to: 267 - 30x = 145.

Now, let's solve for x:

267 - 30x = 145.

To isolate x, we subtract 267 from both sides:

-30x = 145 - 267, -30x = -122.

Next, divide both sides by -30:

x = (-122)/(-30), x = 4 2/15.

Therefore, the solution to the equation 8 9/10 - x = 4 5/6 is x = 4 2/15.
