Answer:
21% of 1 is 0.21
Step-by-step explanation:
Method 1:
[tex]p\%=\dfrac{p}{100}\\\\21\%=\dfrac{21}{100}=0.21[/tex]
21% of 1:
[tex]0.21\cdot1=0.21[/tex]
Method 2:
[tex]\begin{array}{ccc}1&-&100\%\\x&-&21\%\end{array}\right\qquad\text{cross multiply}\\\\100x=(1)(21)\qquad\text{divide both sides by 100}\\\\x=\dfrac{21}{100}\\\\x=0.21[/tex]
