225
22.5
2.25
0.225

Explanation:

Step1: Count decimal places

$0.75$ has $2$ decimal places.

Step2: Adjust product

When we multiplied $75\times3 = 225$, since the original factor $0.75$ has $2$ decimal places, we move the decimal point $2$ places to the left in $225$. So, $225\div100=\frac{225}{100}=2.25$.

Answer:

2.25
