<span>Figure out what is the commonality for each ratio.
There are India stamps in each ratio, so India is the commonality.
Now you simply take the two ratios and multiply them until India has the same amount.
So, Multiply the first by 5 to get a ratio of 25 US to 10 Indian
Multiply the second by 2 to get a ratio of 10 Indian to 2 British
Now that you have "10 Indian" in both ratios, they match up
You have 25 US : 10 Indian : 2 British.
Since the answer is only asking for US and British, you only need 25 US : 2 British</span>
Answer:
1500 students
Step-by-step explanation:
To do this you must figure how many people the university accepts by times the no. of students applying by the percentage that are accepted
10,000 X 60% = 6000 students
You then figure out the number of students that actually enrols by doing
no. of students accepted X 25%
6000 X 25% = 1500 students
D. 32/47
You would subtract 1580 from 640 to get 940. You would then simplify 640/940 to get 32/47.
The table tells you that f(x)=0 at x=-6 and -2
