3,5×0,8 dijadikan pecahan
![]()
Jawaban:
[tex]3.5 \times 0.8 = \frac{35}{10} \times \frac{8}{10} = \frac{280}{100} [/tex]
[tex] = \frac{280}{100} = \frac{280 \div 20}{100 \div 20} = \frac{14}{5} = 2 \ \frac{4}{5}[/tex]
Caranya:
[tex]3,5×0,8 = [/tex]
[tex]3,5 = \frac{35 \div 5}{10 \div 5} = \frac{7}{2} [/tex]
[tex]0,8 = \frac{8 \div 2}{10 \div 2} = \frac{4}{5} [/tex]
[tex] \frac{7}{2} \times \frac{4}{5} = \frac{7 \times 4}{2 \times 5} = \frac{28}{10} \\ \\ = \frac{28 \div 2}{10 \div 2} = \frac{14}{5} = 2 \frac{4}{5} [/tex]
