Let used balloon be x
[tex]\\ \sf\longmapsto x=60\%\:of\:450[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{60}{100}\times 450[/tex]
[tex]\\ \sf\longmapsto x=45(6)[/tex]
[tex]\\ \sf\longmapsto x=270[/tex]
Step-by-step 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.
