✔ 最佳答案
1. 36是900百分之幾?36 / 900 × 100％
= 36 / 900 × 100％ （900 , 100 = 約數 900 = 9 100 = 1 ）
= 36 / 9 × 1％（36÷9）
= 4％
2. 900的36%是多少?
900 × 36％
= 900 × 36 / 100 （900 , 100 = 約數 900 = 9 100 = 1 ）
= 9 × 36
= 324
3. X的36%是900,求X的值。
X × 36 ％ = 900
36X = 900
X = 900 ÷ 36
= 900 ÷ 0.36
= 2500

1: 4% (36/900*100%)
2: 324 (900*0.36) / (900*36%)
3: X*36%=900
X=900/36%
X=900*100/36
X=2500
解算
2500*36%=900
4: 12.5% (0.125的小數點向後走兩個位,記得在最後加上%)
2: 324 (900*0.36) / (900*36%)
3: X*36%=900
X=900/36%
X=900*100/36
X=2500
解算
2500*36%=900
4: 12.5% (0.125的小數點向後走兩個位,記得在最後加上%)
