(1)蘋(píng)果樹(shù)的棵數(shù)是梨樹(shù)的百分之幾?
(2)梨樹(shù)的棵數(shù)比蘋(píng)果樹(shù)多幾分之幾?
(3)蘋(píng)果樹(shù)的棵數(shù)占兩種樹(shù)總棵數(shù)的幾分之幾?
(4)梨樹(shù)的棵數(shù)與蘋(píng)果樹(shù)棵數(shù)的比是多少?
(5)梨樹(shù)的棵數(shù)比蘋(píng)果樹(shù)多占兩種樹(shù)總棵數(shù)的百分之幾?
(6)蘋(píng)果樹(shù)的棵數(shù)比梨樹(shù)棵數(shù)少多少棵?

解:(1)120÷200=60%;
答:蘋(píng)果樹(shù)的棵數(shù)是梨樹(shù)的60%.

(2)(200-120)÷120,
=80÷120,
=;
答:梨樹(shù)的棵數(shù)比蘋(píng)果樹(shù)多

(3)120÷(120+200),
=120÷320,
=;
答:蘋(píng)果樹(shù)的棵數(shù)占兩種樹(shù)總棵數(shù)的

(4)200:120=5:3;
答:梨樹(shù)的棵數(shù)與蘋(píng)果樹(shù)棵數(shù)的比是5:3.

(5)(200-120)÷(120+200),
=80÷320,
=25%;
答:梨樹(shù)的棵數(shù)比蘋(píng)果樹(shù)多占兩種樹(shù)總棵數(shù)的25%.

(6)200-120=80(棵);
答:蘋(píng)果樹(shù)的棵數(shù)比梨樹(shù)棵數(shù)少80棵.
分析:(1)(2)(3)(5)我們運(yùn)用一個(gè)數(shù)比另一個(gè)數(shù)多或少百分之幾的解答方法進(jìn)行解答即可.
(4)運(yùn)用求比的方法進(jìn)行解答即可.
(6)根據(jù)整數(shù)的一個(gè)數(shù)比另一個(gè)數(shù)大或小幾進(jìn)行解答即可.
點(diǎn)評(píng):本題運(yùn)用比多比少的應(yīng)用題的解答方法及求比的解答方法進(jìn)行解答即可.
