[tex] 3.4 = \frac{34}{10} [/tex]

[tex] 2.3 = \frac{23}{10} [/tex]

[tex] \frac{34}{10} \times \frac{23}{10} = \frac{782}{100} = 7.82[/tex]

[tex] \frac{782}{100} \times \frac{5}{10} = \frac{3910}{1000} [/tex]

[tex] \frac{3910}{1000} = \frac{3910 \div 10}{1000 \div 10} = \frac{391}{100} = 3.91[/tex]

Jadi hasil dari 3,4 x 2,3 x 0,5 = 3,91
