DedPeter [7]

Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

$\frac{4}{9}$ ÷ $\frac{1}{2}$

$\frac{4}{9}$ × $\frac{2}{1}$ (Then the the fraction should reciprocal so the values should shift to the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)
