So, by the phrasing, forgive me if I'm wrong, I think the question states that one meter of cloth is $1.36.
A good thing to think about in these kinds of problems is, how much would 2 meters of cloth be? $2.72
How did you get that? By doing: 2*1.36= 2.72
So back the original question: how much is 6 1/4 meters?
6 1/4 * 1.36
(You can convert both to fractions or decimals)
A 1/4 is .25 because 1 divided by 4 is .25.
So: 6.25*1.36= $8.50
