Lynn uses a pencil to divide a string into 10 equal parts. Given that the string is 390 cm long,
- How many markings were made?
- What is the length between any two markings?
- What is the distance between the 1st and 7th marking?
(a)
Number of markings made
= 10 - 1
= 9
(b)
Length between any two markings
= 390 ÷ 10
= 39 cm
(c)
Distance between 1st and 7th marking
= 39 x (7 - 1)
= 39 x 6
= 234 cm
Answer(s): (a) 9 ; (b) 39 cm; (c) 234 cm
