We multiply by #4/4# in this instance to give #76/100# as a fraction, which is equivalent to #0.76# as a decimal.

Explanation:

To create a decimal we need to divide by a power of 10: 10, 100, 1000 and so on.

In this case, we can multiply 25 by 4 to get 100, and whatever we do to the bottom of a fraction we must also do to the top.

(#4/4=1# so we are effectively multiplying by 1)

#19/25 xx 4/4 = 76/100=0.76#
