bambu panjang 4,5 m dipotong 3/4 m dibbuat kentongan 2 1/2 m berapa sisanya
![]()
panjang bambu
4,5 m = 45/10
panjang bambu digunakan
3/4 + 2 1/2 = 3×1/4×1 + 5×2/2×2 = 3/4 + 10/4 = 13/4
sisa bambu
panjang bambu - bambu digunakan
45×2/10×2 - 13×5/4×5 = 90/20 - 65/20 = 25/20 disederhanakan menjadi 5/4 m

jawaban lain
persen → 5×25/4×25 = 125/100 = 125% m
desimal → 5×25/4×25 = 125/100 = 1,25 m
4,5 - (3/4 + 2 1/2)
= 4,5 - (0,75 + 2,5)
= 4,5 - 3,25
= 1,25 m
