Question

同學(xué)們參加秋季造林，共植松樹(shù)45行，每行126棵，植柏樹(shù)324棵，松樹(shù)棵數(shù)比柏樹(shù)棵數(shù)多多少棵？

Answer 1

分析：先計(jì)算出植松樹(shù)的總棵數(shù)，即45×126=5670棵，進(jìn)而減去柏樹(shù)的棵數(shù)，從而問(wèn)題逐步得解．

解答：解：45×126-324
=5670-324
=5346（棵）；
答：松樹(shù)棵數(shù)比柏樹(shù)棵數(shù)多5346棵．

點(diǎn)評(píng)：先計(jì)算出植樹(shù)的總棵數(shù)，是解答本題的關(guān)鍵．
