say that x = 0.888888888... then 10x = 8.8888888... so 10x - x = 8.88888 - 0.88888 therefore 9x = 8 and x = 8/9 hope it helps :)

10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3

x2-10x = 0 x(x-10) = 0 x = 0 or x = 10
The fraction to 0.8888... is:Let x = 0.88888888888....10x = 8.8888888888888...x = 0.8888888888888...9x = 8x = 8/9
say that x = 0.888888888... then 10x = 8.8888888... so 10x - x = 8.88888 - 0.88888 therefore 9x = 8 and x = 8/9 hope it helps :)
10x = 4.44... x = 0.44... 9x = 4 x = 4/9
Changed into what? A fraction? Assuming you mean 0.55555 recurring, then: Let x = 0.55555.... => 10x = 5.5555.... Then 10x - x = 5.5555.... - 0.55555... => 9x = 5 => x = 5/9
5/3 is 1.6666666667 as an improper fraction.
To turn 0.5 repeating into a fraction, we can represent it as a geometric series. Let x = 0.5 repeating. Multiplying x by 10, we get 10x = 5.5555... Subtracting x from 10x, we have 10x - x = 5.5555... - 0.5555..., which simplifies to 9x = 5. Dividing both sides by 9, we get x = 5/9. Therefore, 0.5 repeating can be expressed as the fraction 5/9.
-10x = x-33 -10x-x = -33 -11x = -33 x = 11

Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
To convert the decimal 4.6666 to a fraction, we first note that it is a recurring decimal. To express this as a fraction, we let x = 4.6666. Multiplying x by 10 gives 10x = 46.6666. Subtracting x from 10x gives 9x = 42, and dividing by 9 gives x = 42/9 = 14/3. Therefore, 4.6666 as a fraction is 14/3.
If that is recurring 5 then as a fraction it is 5/9
