Answer:
Step-by-step explanation:
The total length of ribbon = 4½ m = 4.5 m
= 4.5 m x (100 cm/1 m)
= 450 cm
The number of pieces of ribbon, each 4.5 cm long, that can be cut from a length of 4½ m (450 cm) = 450 cm/(4.5 cm/1 piece)
= (450 cm/1)/(4.5 cm/1 piece)
= (450 cm/1)(1 piece/4.5 cm)
= (4500 cm-pieces)/45 cm)
= (4500 cm/45 cm) pieces
= 100 pieces
