#10/25# converted to decimal is #0.40#.

Explanation:

To convert any fraction into decimal, first make the denominator as a power of #10#.

Here in #10/25#, the denominator is #25=5xx5#. If a denominator has #2# and #5# as only prime factors, it is easier to convert it into decimals.

Here as we have two #5's#, if we multiply nemerator and denominator by two #2's# i.e. by #2xx2=4#, we will have hundred in denominator.

Then, #10/25=(10xx4)/(25xx4)=40/100#, which is nothing but #0.40#.

Hence, #10/25# converted to decimal is #0.40#.
