Answer:

133 pieces of 15cm can be cut from the ribbon.

Step-by-Step Explanation:

Length of ribbon = 20 meters

Length needed to be cut = 15 cm

We will convert meters into centimeters.

1 meter = 100 cm

20 meters = 2000 cm

Number of pieces = [tex]\frac{2000}{15}[/tex]

Number of pieces = 133.33

Rounding off to nearest whole number = 133

Hence,

133 pieces of 15cm can be cut from the ribbon.

Elissa can cut 133 ribbons from 20 meters long ribbon and this can be determined by using the unitary method.

Given :

Elisse has 20 meters of ribbon.

The following steps can be used to determine the total number of ribbons of length 15 cm can be cut from 20 meters ribbon:

Step 1 - Remember 1 meter is 100 cm.

Step 2 - If 1m is 100 cm then 20m is equal to:

[tex]=20\times 100[/tex]

= 2000 cm

Step 3 - Elisse cut 15cm long ribbon. So, the total number of ribbons she can cut is:

[tex]=\dfrac{2000}{15}[/tex]

Simplify the above expression.

= 133.334

[tex]\approx[/tex] 133

So, she can cut 133 ribbons from 20 meters long ribbon.
