ujang mmpunyai bmbub3/4 m ucok 1 2/5 m dvgunakan utk mmbuat sangkar spnjang 1 7/10 brpa mter bmbu yg trsisa?

panjang bambu = 3/4 + 1 2/5
= 3/4 + 7/5
= 15/20 + 28/20
= 41/20
digunakan 1 7/10 = 17/10
Bambu tersisa = 41/20 - 17/10
= 41/20 - 34/20
= 7/20 m
= 7/20 x 100 cm. ( 1 m = 100 cm)
= 7/2 x 10 cm
= 35 cm
