Answer:
The answer is 248832
Step-by-step explanation:
if your number was 11/22 the reciprocal would be 22/11. You can think of it as the refliprical.
In an examination, 70% of the candidates passed in English, 80% passed in mathematics, and 10% failed in both subjects. If 144 candidates passed in both, what is the total number of students?
Let the total no of students be 100x
No of students failed =10*100x /100 = 10x
Thus , no of students passed = 100x - 10x = 90x
No of students passed in english = 7* 100x /100 =70x
No of students passed in maths = 8*100x / 100 =80x
Therefore no of students who passed in both = (80x + 70x) - 90x = 60 x
{{ Draw a venn diagram to understand this point ,
Or you could think like this:- when we add no of students passing in m and e individually ,we are counting those students who passed in both twice ,
Thus total students passed will be sum of no of students passed in maths and english individually - those who passed both.
Rearrange this eqn to get the one used above}}
Thus 60x = 144
Or, 100x = (144 * 100)/60=240
Therefore total no of students = 240
Hope you understood

Answer:
20 minutes
Step-by-step explanation:
Remember that
we know that
Hector has 3/4 hour to spend his homework
Convert to minutes
so
1) He wants to spend 1/3 of this time on math homework
To find out the time on math homework, multiply 45 minutes by 1/3
2) He wants to spend 10 minutes of his time on reading homework
3) He wants to spend the remaining time on science homework
The time spend on math homework plus the time spend reading homework, plus the time spend on his science homework must be equal to 45 minutes
Let
x ----> the time spend on his science homework
Solve for x
