Answer:
153.8 I guess... this is your answer
The distance between the two numbers is A. 6 units
Use this formula:
original amount - new amount
———————————————-
original amount
you just plug in the numbers in this formula now and solve
20-11 9
——— = —- = 0.45
20 20
multiply 0.45 by 100 to convert it into a percent
0.45 * 100 = 45
The answer is 45% !!
Answer:
Age of Alice = 25, Age of Jane = 20.
Step-by-step explanation:
Let age of Alice = x
Then age of Jane is 80% of the age of Alice
=> Age of Jane = 80% of x = 80/100 * x = 0.8x
Adding the two ages gives 45.
The two ages are x and 0.8x.
The sum of the two ages is x+ 0.8 x = (1+0.8)x = 1.8x.
=> 1.8 x = 45
Dividing both sides by 1.8, x = 45/1.8
=> x= 25
But x represents the age of Alice.
So age of Alice is 25.
Age of Jane = 0.8* 25 = 20
Verification: Adding the two ages gives 45.
