Answer
$0.75$
Work Step by Step
If we can write a fraction so that its denominator is one of 10,100, 1000,...,
we can easily write it as a decimal number
Using the fact that $4\cdot 25=100,$
$\displaystyle \frac{3}{4}=\frac{3\cdot 25}{4\cdot 25}=\frac{75}{100}$
We write this as a decimal number with two digits after the decimal point:
$= 0.75$
