Khalil has 13.5 M of lanyard he needs to cut the lanyards into pieces that are 90 cm long how many full-length pieces of a lanya
Dmitry [639]

We have been given that Khalil has 13.5 M of lanyard. He needs to cut the lanyards into pieces that are 90 cm long. We are asked to find the number of full-length pieces of a lanyard will Khalil be able to cut.

First of all, we will convert 13.5 meter into cm.

1 meter = 100 cm

13.5 meters = 13.5*100 = 1350 cm.

Now we will divide 1350 by 90 to find number of pieces of lanyard that can be cut from 1350 cm.

\text{Number of full-length pieces of a lanyard}=\frac{1350}{90}

\text{Number of full-length pieces of a lanyard}=15

Therefore, Khalil will be able to cut 15 full-length pieces of a lanyard.
