Diana uses a marker to divide a ribbon into 10 equal parts. Given that the ribbon is 470 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
= 470 ÷ 10
= 47 cm
(c)
Distance between 1st and 7th marking
= 47 x (7 - 1)
= 47 x 6
= 282 cm
Answer(s): (a) 9 ; (b) 47 cm; (c) 282 cm
