Hasil dari 1,25 - 5/6 x 280 % : 1 1/6 adalah... tolong bantuannya ya

≡ diketahui :
⇒1,25 = ⁵/₄

⇒280% = ¹⁴/₅

⇒1¹/₆ = ⁷/₆

≡ penyelesaian :
[tex] = \frac{3}{4} - \frac{5}{6} \times \frac{14}{5} \div \frac{7}{6} \\ \\ = \frac{3}{4} - \frac{14}{6} \div \frac{7}{6} \\ \\ = \frac{3}{4} - \frac{14}{6} \times \frac{6}{7} \\ \\ = \frac{3}{4} - \frac{14}{7} \\ \\ = \frac{21 - 56}{28} \\ \\ = - \frac{35}{28} [/tex]

Jb :

1,25 - 5/6 x 280% ÷ 1 1/6

= 3/4 - 5/6 x 14/5 ÷ 7/6

= 3/4 - 14/6 ÷ 7/6

= 3/4 - 14/6 x 6/7

= 3/4 - 14/7

= ( 21 - 56 )
-----------------
28

= - 35/28 → Sama² Dibagikan Dengan 7
= - 5/4
= - 1 1/2

I Hope This Helps
