900 people attended a football game. If 25% of the people who attended were teenagers, how many teenagers attended the game?

225 Teenagers

Step-by-step explanation:

25 percent *900 =

( 25:100)*900 =

( 25*900):100 =

22500:100 = 225

Now we have: 25 percent of 900 = 225

Question: What is 25 percent of 900?

Percentage solution with steps:

Step 1: Our output value is 900.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 900 = 100%

Step 4: Similarly, x = 25%

Step 5: This results in a pair of simple equations:

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

 =

Step 7: Again, the reciprocal of both sides gives

=  %

⇒  x = 225

Therefore, 25% of 900 is 225

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
