30% = 0.3
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
Solution:
To write percent to decimal, divide the number by 100.
[tex]$30\%=\frac{30}{100}[/tex]
[tex]$=\frac{30\div10}{100\div 10}[/tex]
[tex]$=\frac{3}{10}[/tex]
= 0.3
30% = 0.3
Average use of water each day = 90 gallons
[tex]30\% \ \text{of} \ 90=0.3 \times 90[/tex]
= 27
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
