[tex]2 \frac{1}{2} = \frac{5}{2} \\ 0.57 = \frac{57}{100} \\ 65\% = \frac{65}{100} [/tex]
maka cara menghitungnya :
[tex] = \frac{5}{2} - \frac{57}{100} - \frac{65}{100} \\ = \frac{5 \times 50}{2 \times 50} - \frac{57}{100} - \frac{65}{100} \\ = \frac{250}{100} - \frac{57}{100} - \frac{65}{100} \\ = \frac{193}{100} - \frac{65}{100} \\ = \frac{128}{100} \\ disederhanakan \: menjadi \\ = \frac{32}{25} \\ = 1 \frac{7}{2}
=1,28 [/tex]
