Tiffany had a ribbon of 300 cm long. She tied some balloons on the ribbon. Part of the ribbon and balloons were shown. Each balloon was 14 cm apart from one another.
- What is the length of the ribbon between the fifth and the fourteenth balloon?
- Find the most number of balloons that could be tied on the 300 cm of ribbon with balloons at 14 cm apart from one another.
(a)
Number of intervals between the fifth and the fourteenth balloon
= 14 - 5
= 9
Length of the ribbon between the fifth and the fourteenth balloon
= 9 x 14
= 126 cm
(b)
Sets of 14 cm
= 300 ÷ 14
= 21 r 6
Most number of balloons
= 21 + 1
= 22
Answer(s): (a) 126 cm; (b) 22
