Calculation of the Length of the Entire Ribbon

To calculate the length of the entire ribbon, we need to determine the length of the smaller part of the ribbon. We are given that the larger part of the ribbon is 54 cm long and the ratio between the two parts is 2:3.

Let's assume the length of the smaller part of the ribbon is x cm. According to the given ratio, the length of the larger part of the ribbon is (2/3) * x cm.

To find the length of the entire ribbon, we need to add the lengths of the smaller and larger parts:

Length of the entire ribbon = length of the smaller part + length of the larger part

Length of the entire ribbon = x cm + (2/3) * x cm

Simplifying the equation:

Length of the entire ribbon = (3/3) * x cm + (2/3) * x cm

Length of the entire ribbon = (5/3) * x cm

Now, we can substitute the given length of the larger part of the ribbon (54 cm) into the equation and solve for x:

(5/3) * x cm = 54 cm

To solve for x, we can multiply both sides of the equation by (3/5):

x cm = (54 cm) * (3/5)

Evaluating the expression:

x cm = 32.4 cm

Therefore, the length of the smaller part of the ribbon is 32.4 cm. To find the length of the entire ribbon, we can substitute this value back into the equation:

Length of the entire ribbon = (5/3) * (32.4 cm)

Calculating the length:

Length of the entire ribbon = 54 cm

Therefore, the length of the entire ribbon is 54 cm.
