Question

15．我校有香樟樹(shù)96棵，冬青樹(shù)比香樟樹(shù)的3倍多10棵，冬青樹(shù)比香樟樹(shù)多多少棵？

Answer 1

分析 冬青樹(shù)比香樟樹(shù)的3倍多10棵，用香樟樹(shù)棵數(shù)乘以3，再加上10棵，即為冬青樹(shù)的棵數(shù)；再用冬青樹(shù)的棵數(shù)減去香樟樹(shù)的棵數(shù)，即為冬青樹(shù)比香樟樹(shù)多多少棵．

解答 解：（96×3+10）-96
=（288+10）-96
=298-96
=202（棵）
答：冬青樹(shù)比香樟樹(shù)多202棵．

點(diǎn)評(píng) 解決本題要注意理解倍數(shù)關(guān)系，求一個(gè)數(shù)的幾倍是多少，用乘法計(jì)算．
