Yoko uses a pen to divide a ribbon into 10 equal parts. Given that the ribbon is 280 cm long,
- How many markings were made?
- What is the length between any two markings?
- What is the distance between the 1st and 6th marking?
(a)
Number of markings made
= 10 - 1
= 9
(b)
Length between any two markings
= 280 ÷ 10
= 28 cm
(c)
Distance between 1st and 6th marking
= 28 x (6 - 1)
= 28 x 5
= 140 cm
Answer(s): (a) 9 ; (b) 28 cm; (c) 140 cm
