Hazel uses a marker to divide a streamer into 10 equal parts. Given that the streamer is 400 cm long,
- How many markings were made?
- What is the length between any two markings?
- What is the distance between the 1st and 8th marking?
(a)
Number of markings made
= 10 - 1
= 9
(b)
Length between any two markings
= 400 ÷ 10
= 40 cm
(c)
Distance between 1st and 8th marking
= 40 x (8 - 1)
= 40 x 7
= 280 cm
Answer(s): (a) 9 ; (b) 40 cm; (c) 280 cm
