Write each percent as a fraction and as a mixed number or fraction 325% 480% 0.6%

ExtremeBDS [4]

325%=3.25 which is $\frac{325}{100}$ or $3\frac{25}{100}$ which can be reduced to $3\frac{1}{4}$

480%=4.80 which is $\frac{480}{100}$ or $4\frac{80}{100}$ which can be reduced to $4\frac{4}{5}$

0.6%=0.006 which is $\frac{3}{500}$

I hope this helps.
