Menukar Dari Perpuluhan Ke Peratusan =
Soalan :
0.26
= ( 0 x 100 ) + 26
= 26%

1.52
=( 1 x 100 ) + 52
= 100 + 52
= 152% 

8.96
= ( 8 x 100 ) + 96
= 800 + 96
= 896%

Menukar Dari Pecahan Ke Peratusan = 
Soalan :
18/25
= 18 x 100 ÷ 25
= 1800 ÷ 25
= 72%

1 ( 15 / 25 ) 
= ( 1 = 100 ) + ( 15 x 100 ÷ 24 )
= 100 + ( 1500 ÷ 24 )
= 100 + 62.5
= 162.5%
