The percentage of 4c that is each expression is:
1) 5%
2) 25%
3) 75%
4) 125%
5) (a/c)*50%
What percent of 4c is each expression?
Here 4c represents the 100%, to get the percent of 4c that is each expression, we need to use the equation:
[tex]percentage = \frac{E}{4c}*100 \%[/tex]
Where E is the expression.
Notice that if we use E = 4c we get the trivial percentage:
[tex]percentage = \frac{4c}{4c}*100 \% = 100 \%[/tex]
Now we just need to evaluate the equation for all the given expressions:
1) E = 0.2c
[tex]percentage = \frac{0.2c}{4c}*100 \% = 5 \%[/tex]
2) E = c
[tex]percentage = \frac{c}{4c}*100 \% = 25 \%[/tex]
3) E = 3c
[tex]percentage = \frac{3c}{4c}*100 \% = 75 \%[/tex]
4) E = 5c
[tex]percentage = \frac{5c}{4c}*100 \% = 125 \%[/tex]
5) E = 2a
[tex]percentage = \frac{2a}{4c}*100 \% = \frac{a}{c}*50 \%[/tex]
Here we can't give an exact percentage, because we don't know the relation between c and a.
