Answer:

1/3x + x = 60

Step-by-step explanation: (Solution)

Add.

1/3x + x = 1 1/3x

Change the mixed fraction into improper fraction.

1 1/3x = 4/3x

4/3x = 60

Multiply both sides of the equation by 3.

4/3x × 3 = 60 × 3

4x = 180

Divide both sides of the equation by 4.

4x ÷ 4 = 60 ÷ 4

x = 15

The x is only for the other part.

15 ÷ 1/3

15 × 3

= 45

Therefore, the 2 parts of the 60 cm ribbon are 15 cm and 45 cm.

Hope this helps :)
