1 2/3 –1 =5/3 –1 =2/3 kok bisa 5/3–1= 2/3 tolong ya penjelasannya terima kasih

[tex] = 1 \frac{2}{3} - 1 \\ = \frac{(3 \times 1) + 2}{3} - 1 \\ = \frac{3 + 2}{3} - 1 \\ = \frac{5}{3} - 1[/tex]
Agar bisa di kurangkan penyebut di samakan menjadi 3
[tex] = \frac{5}{3} - \frac{3}{3} \\ = \frac{5 - 3}{3} \\ = \frac{2}{3} [/tex]
Semoga di pahami... ✔

Begini caranya
[tex]1 \frac{2}{3} - 1 = \frac{5}{3} - 1 = \frac{2}{3} \\ = 1 \frac{2}{3} = \frac{5}{3 } \\ = \frac{5}{3} - 1 = \frac{5}{ 3} - ( \frac{1}{1} ) \times 3 \\ = \frac{5}{3} - \frac{3}{3} \\ = \frac{2}{3} [/tex]
Semoga terbantu
