1. (10 points) Calculate: $3752 \div(39 \times 2)+5030 \div(39 \times 10)=$
【Analysis】According to the properties of division, the original expression $=3752 \div 2 \div 39+5030 \div 10 \div 39=1876 \div 39+503 \div 39=$ $(1876+503) \div 39=2379 \div 39=61$, solve accordingly.

【Solution】Solution: $3752 \div(39 \times 2)+5030 \div(39 \times 10)$
$$
\begin{array}{l}
=3752 \div 2 \div 39+5030 \div 10 \div 39 \\
=1876 \div 39+503 \div 39 \\
=(1876+503) \div 39 \\
=2379 \div 39 \\
=61
\end{array}
$$

Therefore, the answer is: 61.
