Tolong dong ka nomer 1/2 aja dulu jga gpp

Penjelasan dengan langkah-langkah:

No 3 :

$luas = p times l \ \ 360 = 28.8 times l \ \ 360 = frac{288}{10} times l \ \ 360 times frac{10}{288 } = l \ \ frac{3600}{288} = l \ \ frac{25}{2 } = l \ \ 12.5 : : meter = l$

No 4 :

$5 frac{1}{2} = frac{11}{2} \ \ frac{11}{2} div frac{1}{4} = frac{11}{2} times 4 = 22 : siswa$

No 5 :

$12 frac{3}{4} = frac{51}{4} \ \ frac{51}{4} times frac{1}{4} = frac{51}{16} = 3 frac{3}{16} : kg$

No 1 :

2,5 = 25/10 = 5/2

5/2 × 13/4 = 65/8

65/8 = 65/8 × 125/125 = 8125/1000 = 8,125 liter
