Use your desmos calculator!

Change 0.86 to a percent 

0.86 x 100

86%

Don't forget the percent sign! (%)

Requires you to simplify - use division to make a fraction smaller

Use your desmos calculator!

Change 90% into a fraction!

Place the percent over 100  $\frac{90}{100}$  

SIMPLIFY!

 $\frac{90}{100}\div\frac{10}{10}=\frac{9}{10}$  

Requires you to simplify - use division to make a fraction smaller

Use your desmos calculator!

Change 64% into a fraction!

Place the percent over 100  $\frac{64}{100}$  

SIMPLIFY!

 $\frac{64}{100}\div\frac{4}{4}=\frac{16}{25}$  

Follow the triangle, start at fraction and convert to a decimal

 $4\div5=0.8$  

Change the decimal to a percent!

Move the decimal two spaces to the right OR multiply by 100

0.8 x 100 =80%

Dont forget your % sign!

Follow the triangle, start at decimal and convert to a percent 

0.75 x 100 = 75% or move two places to the right

Change the percent to a fraction!

 $\frac{\%}{100}=\frac{75}{100}$  

SIMPLIFY!

 $\frac{75}{100}\div\frac{25}{25}=\frac{3}{4}$  

Follow the triangle, start at percent and convert to a fraction

 $\frac{\%}{100}=\frac{23}{100}$  

Divide the numerator by the denominator to change to a decimal

 $23\div100=0.23$
