Tina uses a crayon to divide a ribbon into 10 equal parts. Given that the ribbon is 420 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
= 420 ÷ 10
= 42 cm
(c)
Distance between 1st and 4th marking
= 42 x (4 - 1)
= 42 x 3
= 126 cm
Answer(s): (a) 9 ; (b) 42 cm; (c) 126 cm
