一、Fill in the Blanks (20 questions in total, 3 points each, full score 60 points)
1. (3 points) Calculate: $1.25 \times \frac{2}{9}+1 \frac{1}{9} \times 1 \frac{1}{4}-125 \% \times \frac{1}{3}=$ $\qquad$
【Solution】Solve: $1.25 \times \frac{2}{9}+1 \frac{1}{9} \times 1 \frac{1}{4}-125\% \times \frac{1}{3}$
$$
\begin{array}{l}
=\frac{5}{4} \times \frac{2}{9}+\frac{10}{9} \times \frac{5}{4}-\frac{5}{4} \times \frac{1}{3}, \\
=\frac{5}{4} \times\left(\frac{2}{9}+\frac{10}{9}-\frac{1}{3}\right), \\
=\frac{5}{4} \times 1, \\
=\frac{5}{4} .
\end{array}
$$

Therefore, the answer is: $\frac{5}{4}$
