Answer 1

Let used balloon be x

`\\ \sf\longmapsto x=60\%\:of\:450`

`\\ \sf\longmapsto x=(60)/(100)* 450`

`\\ \sf\longmapsto x=45(6)`

`\\ \sf\longmapsto x=270`

Answer 2

Explanation:

Solution,

• Let the number of used balloons be x,

Given:-

• Total number of balloons= 450
• Used percentage of balloons= 60%

Now,

Number of used balloons(x)=

• 60% of 450
• 60/100×450
• 270

Hence, 270 balloons were used.
