Question

【題目】果園里有桃樹(shù)60棵，杏樹(shù)75棵．桃樹(shù)棵數(shù)比杏樹(shù)少百分之幾？杏樹(shù)棵數(shù)比桃樹(shù)多百分之幾？

Answer 1

【答案】解：（75﹣60）÷75

=15÷75

=20%

（75﹣60）÷60

=15÷60

=25%

答：桃樹(shù)棵樹(shù)比杏樹(shù)少20%，杏樹(shù)棵樹(shù)比桃樹(shù)多25%。

【解析】求桃樹(shù)棵數(shù)比杏樹(shù)少百分之幾，用桃樹(shù)比杏樹(shù)少的棵數(shù)除以杏樹(shù)棵數(shù)即可；同理，求杏樹(shù)的棵數(shù)比桃樹(shù)多百分之幾，把桃樹(shù)的棵數(shù)看作單位“1”，根據(jù)“（大數(shù)﹣小數(shù)）÷單位“1”的量”進(jìn)行解答。
