Hello!

Answer:


\Large \boxed{\sf x = (81)/(5) }

Explanation:

→ We want to find 9 divided by what equals 5/9.

→ Let x be our number.

→ So we have this equation:


\sf 9 / x = (5)/(9)

→ Let's solve this equation:

Simplify the left side:


\sf (9)/(x)= (5)/(9)

Multiply both sides by 9x:


\sf (9)/(x)* 9x= (5)/(9) * 9x

Simplify both sides:


\sf 9 * 9 = x * 5


\sf 81=5x

Divide both sides by 5:


\sf(81)/(5) = (5x)/(5)

Simplify both sides:


\boxed{\sf x = (81)/(5) }

Conclusion:

The number is 81/5.

Answer:


(81)/(5)

Explanation:

let x be what 9 is divided by to equal
(5)/(9) , then


(9)/(x) =
(5)/(9) ( cross- multiply )

5x = 9 × 9 = 81 ( divide both sides by 5 )


(5)/(5) x =
(81)/(5) , that is

x =
(81)/(5)
