Bab Pecahan

Penyelesaian :
[tex]1.25 - \frac{2}{3} + 1.75 \\ = \frac{125}{100} - \frac{2}{3} + \frac{175}{100} \\ = \frac{375 - 200 + 525}{300} \\ = \frac{700}{300} = 2 \frac{100}{300} = 2 \frac{1}{3} \: kg[/tex]
Jadi tepung Velia sekarang ada 2 1/3 kg
Pilihan A

Good Luck Friends !

Halo, selamat sore kawan :)

Pembahasan :

[tex]1.25 = \frac{125}{100} = \frac{125 \div 25}{100 \div 25} = \frac{5}{4} [/tex]

[tex]1.75 = \frac{175}{100} = \frac{175 \div 25}{100 \div 25} = \frac{7}{4} [/tex]

[tex] \frac{5}{4} - \frac{2}{3} = \frac{(5 \times 3) + (2 \times 4)}{12} = \frac{15 - 8}{12} = \frac{7}{12} [/tex]

[tex] \frac{7}{12} + \frac{7}{4} = \frac{7 + (7 \times 3)}{12} = \frac{7 + 21}{12} = \frac{28}{12} [/tex]

[tex] \frac{28}{12} = \frac{28 \div 4}{12 \div 4} = \frac{7}{3} = 2 \frac{1}{3} \: kg[/tex]

Jadi, jawabannya adalah :

[tex]2 \frac{1}{3} \: kg[/tex]
