In Justin's school 0.825 of the students participate in a sport. If there are 1000 students in Justin's school, how many partici
ikadub [295]

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

\implies  \frac{0.825}{x}= \frac{1}{1000}

By cross multiplying we obtain,

x=0.825 \times 1000

We finally simplify to arrive at

x=825

Hence the number of students who participated in the sport is 825

Gnoma [55]
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.
