. Maria spent 1\9of the money her grandparents gave her on an adventure book. She also spent 1/3 of the money on a bag of candy. What fraction of the payment has Maria spent?
Answers
Answer:
Step-by-step explanation:
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
Hope this helps you :-)

Using percentage, the numbers of juniors will allowed to attend an event is 50.
What is percentage?
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

x=90
y=10
Explanation:
Let x be equal to the first number.
Let y be equal to the second number.
We know that the sum of the two numbers is 100, so we can say that x+y=100.
We also know that the difference of the two numbers is 80, so we can also say that x-y=80
And now we have our two equations:
x+y=100
x-y=80
To find x and y, we first solve for one of the variables and plug it into one of the two equations to solve for the other. In this case, the easiest way to approach this question is to add both of the equations to cancel y out and solve for x (please check the picture attached for a better representation).
x+y=100
x-y=80
-> 2x=180
2x=180
Divide both sides by 2
2x/2=180/2
x=90
Now that we have found the value of the first number, x, we can plug it in to either of our two original equations to solve for y.
x+y=100
90+y=100
Subtract both sides by 90
90+y-90=100-90
y=10
Therefore, the value of x is 90 and the value of y is 10. Their sum is 100 and their difference is 80.
I hope this helps!
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.
