<h2>Problem:</h2>

Choose all the expressions that are equal to 5/9×8.

A. 9÷5×8

B. 8/9×5

C. 5÷8×9

D. 5×1/9×8

E. 5×8

<h2>Solution:</h2>

$\purple{ \frac{5}{9} \times 8 = \frac{40}{9} = 4 \: \frac{4}{9} }$

$\red{9 \div 5 \times 8 = \frac{9}{5} \times 8 = \frac{72}{5} = 14 \: \frac{2}{5} }$

$\red{ \frac{8}{9} \times 5 = \frac{40}{9} = \boxed{4 \: \frac{4}{9} }}$

$\red{5 \div 8 \times 9 = \frac{5}{8} \times 9 = \frac{45}{8} = 5 \: \frac{5}{8} }$

$\red{5 \times \frac{1}{9} \times 8 = \frac{5}{9} \times 8 = \frac{40}{9} = \boxed{4 \: \frac{4}{9} }}$

$\red{5 \times 8 = 40}$
