Answer to this math question
gladu [14]

Answer:

4\frac{2}{3}

Step-by-step explanation:

This is a recurring decimal.

Let x = 4.666666...                 ⇒ (1)

  10x = 46.66666...                     ⇒ (2)

Subtract equation (1) from equation (2)

    10x = 46.66666..

   -<u>  x = 4.666666...  </u>

    <u>  9x = 42.0000.....</u>

<u />

9x = 42

  x =  42/9

      = 14/3

       =4\frac{2}{3}
