The fraction of the money that Maria spent on an adventure book =
The fraction of the money that Maria spent on a bag of candy =
Now we have to find the total fraction of the money that Maria spent.
For that we have to add those 2 fractions together.
Let us solve now.
There fore, the fraction of the payment has Maria spent is

Using percentage, the numbers of juniors will allowed to attend an event is 50.
Percentage is "fraction or ratio, in which value of whole is 100".
According to the question,
The principal approved the event for 200 students. Number of juniors will be 25% of number of seniors.
Suppose 100% of student is 200 and then 25% of student will be
100% = 200
25% = x
100x = (200) (25) [cross multiplication]
x = 50.
Hence, the principal allowed number of student to attend an event is 50.

Answer:
First you do number of students being approved by the principal times the number of juniors allowed over 100.
This simply means that 200*25/100=50
Answer:
The numbers are 90 and 10.
Step-by-step explanation:
Let the two numbers are x and y.
It has been given that sum of two numbers is 100. Hence, we have the equation,
x + y = 100 .........(i)
Now, the difference of these two numbers is 80. Thus, second equation is
x - y = 180......(ii)
Add equation (i) and (ii)
x + y + x - y = 100 + 80
2x = 180
Divide both sides by 2
x = 90
Substitute this value in (i)
90 + y = 100
y = 100- 90
y = 10
Therefore, the numbers are 90 and 10.
