Bab : Pecahan

Diketahui :
- 2/5
- 1 3/4

Ditanya :
- 2/5 + 1 3/4 = ......?

Penyelesaian :

[tex] \frac{2}{5} +1 \frac{3}{4} \\ = \frac{2}{5} + \frac{(4 \times 1 + 3)}{4} \\ = \frac{2}{5} + \frac{(4 + 3)}{4} \\ = \frac{2}{5} + \frac{7}{4} \\ = \frac{(20 \div 5 \times 2) + (20 \div 4 \times 7)}{20} \\ = \frac{(4 \times 2) + (5 \times 7)}{20} \\ = \frac{8 + 35}{20} \\ = \frac{43}{20} \\ = 2 \frac{3}{20} \\ = 2.15[/tex]

Maaf Kalau Salah
