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
25% of 125
0.25 (125) = 31.25

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