4/9x - 1/9 is an expression, not an equation. An expression cannot be solved.
Well if it's the hardest way to solve this decimals. I use this tricky way to get the decimal number. i used the convert fraction; for ex: the fraction of 8/12. you have to divide 8 by 12 like this: 8 ÷12 = 0.6666666666 * USE YOUR CALCULATOR TO SOLVE THIS * so the decimal form of 8/12 is 0.6666666 . ---------------- Hope that helps, Mrs. Yung.
57 is an integer and so there is no sensible way to represent it as a proper fraction.
250 is an integer and so there is no sensible way of writing it as a fraction or mixed number.
16 is an integer and so there is no sensible way to represent it as a mixed fraction.
510 is an integer and so there is no sensible way of writing it as a fraction or mixed number.
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
0.09 = 9/100 so 0.09x = 9x/100
9x4= 36 36x25180= 906480 so therefore your answer is 906,480
There is no need to do so.
multiply the nos., 2(9), the answer is 18. then, multiply the variables, x(x), the answer is x2 so the answer is: 18x2
Let the numerator be x, so the denominator is x + 4. So we have:x/(x + 4) = 9/15 (cross multiply)15x = 9(x + 4)15x = 9x + 3615x - 9x = 9x - 9x + 366x = 366x/6 = 36/6x = 6x + 4 = 6 + 4 = 10Sine the numerator is 6 and the denominator is 10, then the fraction is 6/10, which in the simplest form is equal to 3/5.Since 9/15 in the simplest form is also equal to 3/5, then 6/10 is equivalent to 9/15.Thus, 6/10 is the required fraction.
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
(the fraction bar means divide) so you just do 6 divided by 1 =6
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
9x+3y=-68 -2x+y=18 We are asked to solve with substitution so we first write y=18+2x. Let us substitute this into the first equation. 9x+3(18+2x)=-68 9x+54+6x=-68 15x=-68-54=-122 so x=-122/15 and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15 So the solution is (-122/15,26/15) which is an ordered pair.

you would not change it back to a improper fraction you would solve it to a proper fraction so it could be looking like this 19 ___ 22
