Question

Six nickels is what percent of $1.00?

Answer 1

`1\ dollar=20\ nickels\\\\20\ nickels\ \rightarrow\ \ \ 100\%\\6\ nickels\ \rightarrow\ \ \ x\\\\x= \frac{\big{6\cdot 100\%}}{\big{20}} \ \ \ \Rightarrow\ \ \ x=30 \%`

Answer 2

1 nickel = $0.05

6 nickels = 6*($0.05) = $0.30

$0.30/$1.00 = (30 ¢)/(100 ¢)

30/100 = 30%

answer is 30%
