25% of 125?
160 is what % of 140?
9,550 is 5% of what number?

Sagot :

1)  Change 25% to decimal = 0.25
      25% of 125
      0.25 (125) = 31.25

2) 140 (n) = 160
     140n/140 = 160/140
     n = 1.14 x 100  (Change decimal to percent by multiplying
                                    decimal by 100)
     n  ≈ 114 %

3)  Change 5% to decimal = 0.05
     0.05 (n) = 9,550
     0.05n/0.05 = 9,550/0.05
     n = 191,000
Percentage (P) ~ Base (B) ~ Rate (R)

P = BR or base × rate
B = P ÷ R
R = P ÷ B

1) You need to find the Percentage
    125 × 25% or 0.25 = 31.25

2) You need to find the Rate
     160 ÷ 140 = 1.14 or 114%

3) You need to find the Base
    9 550 ÷ 0.05 (5%) = 191 000

You need to analyze the question/problem to solve it ☺ 
Clue words:
Base = given date + of + base/number
Percentage = percentage + is + other data
Rate = %
