hasil dari [tex]1.2 \div \frac{2}{5} \times 1 \frac{3}{4} [/tex]

1,2 ÷ 2/5 × 1 3/4
Jadikan pecahan biasa
12/10 ÷ 2/5 × 7/4
12/10 × 5/2 × 7/4
420/80 = 5,25

Penyelesaian :
[tex]1.2 \div \frac{2}{5} \times 1 \frac{3}{4} \\ = \frac{12}{10} \times \frac{5}{2} \times \frac{7}{4} \\ = \frac{420}{80} = \frac{42}{8} = 5 \frac{2}{8} = 5\frac{1}{4 } = 5,25[/tex]

Good Luck :)
