Answer:
25% of students voted for the athlete
Step-by-step explanation:
First you need to know how many students are in total. In this case there is 60, 15+45
Then you write it as a fraction

because 15 voted for athlete out of the 60 students.
After this you need to divide 15÷60 which is . 25 then you transform that number into a percent which is 25%
Answer:
Let us assume the total number of students surveyed = x
Then
Number of students preferring red = x/4
Number of students preferring blue = x/8
Then
Number of students remaining = x - [(x/4) + (x/8)]
=x - [(2x + x)/8)
= x - (3x/8)
= (8x - 3x)/8
= 5x/8
Number of students preferring the color green = (3/5) * (5x/8)
= 3x/8
We also know that the total number of students preferring the color green is 15
So
3x/8 = 15
3x = 15 * 8
x = (15 * 8)/3
= 5 * 8
= 40
So in total 40 students were surveyed. I hope the procedure is clear to you.

Answer:
2203.20 pesos
Step-by-step explanation:
Joe's original amount was $200
#We convert this amount to $CDN:

Joe now has to convert the Canadian dollars to Mexican pesos(at a rate of 10.8 pesos per $1 CDN):

Hence, he gets a total of 2203.20 pesos in exchange for his Canadian dollars.
