Three math questions. I answered 2 of them, tell me if they are right or not please?

The last question...I'm not sure how to solve, please help

The Major League Baseball regular season consists of 162 games. After playing 54 of their games, your favorite team has won 26 wins.
1. If this trend continues, how many wins will your team have at the end of the season?
My answer:
162 games
162 - 54 games = 108 games left
They have 26 wins
162 divided by 54 = 3
3 x 26 = 78 wins.

2. What is the percentage of games won by the team so far this season? (Round to the nearest tenth of a percent.)
My answer:
26 divided by 54 =0.48
Rounded = .50%

3. Use your answer to question 1 to find the percentage of games that the team is projected to win for the entire season. (Round to the nearest tenth of a percent.)

Number 3 is the one I'm having trouble figuring out so please explain it to me, thanks

#1). Your answer is correct, but I'm having some trouble
following how you came to it. I think this would have been
a perfect opportunity to use a proportion.

(26 wins so far)/(54 games so far) = ('x' total wins)/(162 total games) .

Cross multiply the proportion: 54x = (162 x 26)

Divide each side by 54: x = (162 x 26) / (54) = 78 total wins.

#2). You need to be a bit more careful with your percents.

26 divided by 54 = 0.4814...

= 48.14 % .

Rounded to the nearest tenth of a percent:

48.14 % ==> 48.1 % .

#3).

In #1, you calculated that the team would win 78 games
out of the 162 in the whole season. Now, #3 is asking you
what that percentage will be.

Percentage = (games won) / (games played)

= (78) / (162)

Go ahead and do that division now, and be surprised.
Be very surprised !


How did you calculate the 78 wins for the whole season
in #1 ? How can anyone predict how many they'll win in
the future ? Realistically, they can't. But for the sake of
math, the question gave you a very powerful tool to use.

The question said "If this trend continues ... ".
What's the trend ?
The trend is winning 26 of every 54 games they play.

In #2, you found that this trend translated into 48.1% .

"If this trend continues", then they'll continue to win 48.1%
of all the games they play.
