Answer:
18
Step-by-step explanation:
Number of pieces = Length of ribbon/Length of each piece
= (13½) ÷ (¾)
Convert the mixed number to an improper fraction
No. = (²⁷/₂) ÷ (¾)
Invert the proper fraction and change division to multiplication
No. = ²⁷/₂ × ⁴/₃
Cancel the 2s
No. = 27 × ⅔
Cancel the 3s
No. = 9 × 2
No. = 18
