Question

Procenty przedstaw w postaci ułamków zwykłych nieskracalnych. a) b) c) 1%= 15%= 120%= 20%= 60%= 225%= 80%= 75%= 350%=

Answer 1

1 % = 1/100 

 

15 % = 15/100 = 3/20 

 

120 % = 120/100 = 1 i 20/100  = 1 i 1/5 

 

20 % = 20/100 = 1/5 

 

225 % = 225/100 = 45/20 = 9/4 = 2 i 1/4 

 

80 % = 80/100 = 4/5 

 

75 % = 75/100 = 3/4 

 

350 % = 350/100 = 35/10 = 7/2 = 3 i 1/2  

Answer 2

1% =   \frac{1}{100} 

15% =  15/100 

120 % = 120/100 = 6/5 =  1 \frac{1}{5} 

20 % = 20/100 =   \frac{1}{5} 

60 % =   \frac{60}{100} =   \frac{3}{5} 

 

225% =  \frac{225}{100} =   \frac{9}{5} 

 

 80% =   \frac{4}{5} 

 

 75% =   \frac{75}{100} 

350 % =   \frac{7}{2}
