Question

.

Write an equation and solve. Round to the nearest hundredth where necessary.

9 is what percent of 50?


50 = 9 • n; 5.6%

50 = 9 • n; 15.3%

9 = n • 50; 19.8%

9 = n • 50; 18%

Answer 1

`\sf Hello!`


`\sf Let\: the \:required` %
`\sf be\: x`


`\sf Then,`


`\sf x` % ×
`\sf 50 = \sf 9`

⇒
`(\sf x)/(\sf 100) × \sf 50 = \sf 9`

⇒
`(\sf x)/(\sf 2) = \sf 9`

⇒
`\sf X = \sf 9 × 2`

⇒
`\boxed{\sf x = 18}`


`\sf Therefore,`

`\sf D.\: 18` %
`\sf of \:50\: is \:9`
