Answer:
825
Step-by-step explanation:
Let the number of students who participated in the sport be x, which is equivalent to 0.825
The total number of students in the school is equivalent to 1
Expressing mathematically,we obtain
0.825:x=1:1000
By cross multiplying we obtain,
We finally simplify to arrive at
Hence the number of students who participated in the sport is 825
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
