Yoko uses a pencil to divide a streamer into 10 equal parts. Given that the streamer is 250 cm long,
- How many markings were made?
- What is the length between any two markings?
- What is the distance between the 1st and 4th marking?
(a)
Number of markings made
= 10 - 1
= 9
(b)
Length between any two markings
= 250 ÷ 10
= 25 cm
(c)
Distance between 1st and 4th marking
= 25 x (4 - 1)
= 25 x 3
= 75 cm
Answer(s): (a) 9 ; (b) 25 cm; (c) 75 cm
