4 1/2x1 1/6:1/8=.TOLONG YA KAK PAKE CARANYA

Mapel : Matematika
Bab : Pecahan

Diketahui :
- 4 1/2 = 9/2
- 1 1/6 = 7/6
- 1/8

Ditanya :
- 4 1/2 × 1 1/6 ÷ 1/8 = .....?

Penyelesaian :

[tex]4 \frac{1}{2} \times 1 \frac{1}{6} \div \frac{1}{8} \\ = \frac{9}{2} \times \frac{7}{6} \times \frac{8}{1} \\ = \frac{(9 \div 3)}{2} \times \frac{7}{(6 \div 3)} \times \frac{8}{1} \\ = \frac{3}{2} \times \frac{7}{2} \times \frac{8}{1} \\ = \frac{21}{4} \times \frac{8}{1} \\ = \frac{21}{(4 \div 4)} \times \frac{(8 \div 4)}{1} \\ = \frac{21}{1} \times \frac{2}{1} \\ = 42[/tex]
