Question

Jess needs 200 pieces of ribbon, each of length 110cm, to decorate a room for a party. Ribbon is sold in rolls of 25m each.

What is the least number of rolls of ribbon that Jess needs to buy?

Answer 1

Jess needs 200 pieces of ribbon.

Each piece of ribbon has a length of 110 cm.

First, let's convert the length of the ribbon pieces to meters:

110 cm = 110/100 = 1.1 m

let's calculate the total length of ribbon required:

Total length = 200 pieces × 1.1 m/piece = 220 m

calculate the number of rolls of ribbon Jess needs to buy:

Length per roll = 25 m

Number of rolls = 220 m / 25 m

Number of rolls = 220 / 25 = 8.8

he will have to buy 9 rolls
