Answer: B

Step-by-step explanation: All you have to do is plug in the numbers and solve the equation. B is not correct, because 35+40(9) is not equal to 355.

\frac{4}{9} ÷ \frac{2}{3}

First, apply the rule: a ÷ \frac{b}{c} = a × \frac{c}{b}
\frac{4}{9} × \frac{3}{2}
Second, apply the rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd}
\frac{4x3}{9x2}
Third, multiply 4 × 3 to get 12, and 9 × 2 to get 18.
\frac{12}{18}
Fourth, find the GCF of 12 and 18.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18
The GCF is 6.
Fifth, divide the numerator by the GCF. 
12 ÷ 6 = 2
Sixth, divide the denominator by the GCF. 
18 ÷ 6 = 3
Seventh, rewrite your fraction.
\frac{2}{3}

Answer as fraction: \frac{2}{3}
Answer as decimal: 0.6667
