[tex]1 \frac{3}{4} kg[/tex]
kemudian Bibi membeli lagi
[tex] 2\frac{1}{2} kg[/tex]
Beras tersebut dimasak 0,2 kg . sisa beras bibi sekarang adalah
1 3/4 + 2 1/2 - 0,2
7/4 + 5/2- 2/10
penyebut disamakan terlebih dahulu
7/4 = 7×5/4×5 = 35/20
5/2 = 5×10/2×10 = 50/20
2/10 = 2×2/10×2 = 4/20
= 35+50-4/20 = 81/20 kg atau 4,05 kg
[tex]1 \frac{3}{4} kg + 2 \frac{1}{2} kg \: - 0.2 \: kg[/tex]
[tex] \frac{1 \times 4 + 3}{4} + \frac{2 \times 2 + 1}{2} - \frac{2}{10} [/tex]
[tex] \frac{7}{4} + \frac{5}{2} - \frac{2}{10} [/tex]
[tex] \frac{7 \times 5}{4 \times 5} + \frac{5 \times 10}{2 \times 10} - \frac{2 \times 2}{10 \times 2} [/tex]
[tex] \frac{35}{20} + \frac{50}{20} - \frac{4}{20} [/tex]
[tex] \frac{35 + 50 - 4}{20} [/tex]
[tex] \frac{85 - 4}{20} [/tex]
[tex] \frac{81}{20} [/tex]
[tex]4 \frac{1}{20} kg[/tex]
