Kallah needs to buy ribbon for a sewing project. the fabric store charges 2 dollars per meter. how much will it cost kallah to buy on ribbon that is 75cm long?

The charge is $2/m.

We need to find how much money it costs for 75cm.
First let's change 75cm to m. There are 100cm to m.
.

Now we can create a proportion to find how much it costs for a 0.75m ribbon. Then we solve it by cross multiplying.
For some reason I can't put the dollar sign ($) in front of the 2.


It costs $1.50 to buy a ribbon 0.75m, or 75 cm long.
