Rate- is the number compared to 100. It is usually has neither a percent sign(%) or word "percent" with it.
We can solve the problem in three ways.
Example:
Question: 36 is what percent of 60?
Think: n% of 60=36
| | |
RATE BASE PERCENTAGE
a. USING FRACTION
n% of 60=36 *write rate as a fraction
|
n x 60=36
___
100
60n = 36x100
60n = 3,600
60n = 3,600 * 3,600 divided by 60
___ _____
60 60
n= 60- ( ANSWER)
b. USING A PROPORTION
Rate= Percentage
| Base (Multiply 100 to 36)
100x36= 3,600
n 36 n: 100 = 36 : 60
___= ____ (Multiply n to 60)
100 60 nx60= 60n
60n = 3,600
60n = 3,600
____ = _____ * 3,600 divided by 60
60 60
n=60- (Answer)
c. USING THE FORMULA
Rate= Percentage
Base
= 36
___ ( *36 divided by 60)= 0.6
60 * make 0.6 into 60%
ANSWER: 60
FINAL ANSWER: 36 is 60% of 60
Base (b)- is the number or amount that represents the whole or the entire amount.
Question: Cesar has 72 foreign stamps in his collection. If this is 16% of his collection, how many stamps is his total collection?
We can solve the problem in two ways.
Formula: Base = Percentage
Rate
Think: 16% of n = 72
| | |
Rate Base Percentage
a. USE THE RATIO AND PROPORTION
16 72
____ = ____
100 n
. Find the missing term of the proportion. Use cross products.
16 72
=
100 n
16n= 7,200 * write the equation
16n 7,200
__ = _____ * divide both by 16
16 16
n= 450
b. USE THE FORMULA
Base = Percentage
Rate
= 72
16% *Change percent to decimal
= 72
0.16 ( * 72 divided by 0.16) = 450
B= 450
ANSWER: 450
FINAL ANSWER: Cesar has a total of 450 stamp in his collection.
Three ways po yung sa rate pamilian niyo nalang pati na rin sa base pamilian niyo po yung two ways. Pero kung ang example na tinutukoy niyo po is yung literal na example ito po.
Rate Base
50% 100
60% 600
But if yung hanap niyo is parang question na example. I copy niyo nalang po yung question sa itaas.
