We cannot cut any pieces from the 1/4yard string as it is smaller than the 3/5 yard pieces we want to cut.
<u>SOLUTION: </u>
It is given to us that a worker cut pieces of string that are each 3/5 yard in length.
We have been asked to find out how many pieces of string can the worker cut from a piece of string that is 1/4 yard in length.
The total length of the string available for cutting is yard.
We shall convert into decimal form for the simplicity of the calculation. Which gives us:
= 0.25 yard
Now the small pieces that want to be cut of 0.25 yard are given as yards. So, now we convert
yard into decimal as well for uniformity.
= 0.6 yard
So from the calculations we can see that 0.25 yard is smaller than 0.6 yard.
Therefore, we cannot cut any pieces from the yard string as it is smaller than the pieces we want to cut.
