Penjelasan dengan langkah-langkah:

dipakai = dikurangi = mines = -

dibagikan = bagi = ÷

bu Tuti punya 9 meter kain , lalu dipakai 2 1/3 ..

lalu dipakai lagi 2 1/2.. sisa nya dibagikan ke 3 anak, jumlah kain masing masing anak sama

rumus =

(9 - 2 1/3 - 2 1/2) ÷ 3 = jumlah kain masing masing anak

2 1/3 = (3 × 2 +1) / 3= 10/3

2 1/2 = (2 × 2 + 1) /2 = 5/2

9 - 10/3 - 5/2

5/2 = (5 × 3 / 2 × 3) = 15 / 6

10/3 = (10 × 2 / 3 × 2) = 20/6

9 = 9/1 = (9 × 6 / 1 × 6) = 54/6

54/6 - 20/6 - 15/6 = (54 - 20 - 15) /6

= 19 / 6

sisa kain = 19 / 6

sisa kain ÷ total anak = jumlah kain masing masing anak

= 19/6 ÷ 3 = 19/6 ÷ 3/1

= 19/6 × 1/3

= 19/18

= 1 1/18 m

jumlah kain masing masing anak = 1 1/18 m

atau 19/18 m

semoga terbantu, maaf kalau salah ya

tapi saya usahakan supaya hasil jawabannya benar
