Answer 1

Problem:

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

Solution:

`\purple{ (5)/(9) * 8 = (40)/(9) = 4 \: (4)/(9) }`

`\red{9 / 5 * 8 = (9)/(5) * 8 = (72)/(5) = 14 \: (2)/(5) }`

`\red{ (8)/(9) * 5 = (40)/(9) = \boxed{4 \: (4)/(9) }}`

`\red{5 / 8 * 9 = (5)/(8) * 9 = (45)/(8) = 5 \: (5)/(8) }`

`\red{5 * (1)/(9) * 8 = (5)/(9) * 8 = (40)/(9) = \boxed{4 \: (4)/(9) }}`

`\red{5 * 8 = 40}`
