1. Charlie is a florist. He cuts lengths of ribbon to go around vases. Each length of ribbon must be 70 cm. Charlie has a roll of ribbon which is 15 meters in length. How many 70 cm lengths of ribbon can Charlie cut from the roll?

Answer :

Let's find out how many 70 cm lengths of ribbon Charlie can cut from a 15-meter roll of ribbon.

1. Convert the roll length from meters to centimeters:
- Since 1 meter is equal to 100 centimeters, 15 meters is the same as [tex]\(15 \times 100 = 1500\)[/tex] centimeters.

2. Determine how many 70 cm lengths can be cut:
- We want to find out how many times 70 cm can fit into 1500 cm. To do this, divide the total length of the ribbon roll by the length of each piece needed:
[tex]\[
\frac{1500 \text{ cm}}{70 \text{ cm}} = 21.4285714286
\][/tex]
- Since Charlie can only cut full lengths of ribbon, we take the whole number part of the division. This means Charlie can cut 21 full lengths of ribbon, each 70 cm long.

Therefore, Charlie can cut 21 lengths of ribbon from the roll.
