8th grade math homework help!?
Okay, I need help with these two problems (I did the rest so Im not like lazy, okay?):
A basketball league has 288 players and 24 teams, with an equal number of players per team. If the number of teams is reduced by 6 but the total of players stays the same there will be ____ players per team.
a) 6 more
b) 4 more
c) 4 fewer
d) 6 fewer
Indentify the odd number(s) in each list of numbers:
4, 6, 8, 16, 18, 20, 49, 81, 32.
Thanks soo much!
My parents didnt even know, hahaa :].
ok
1) Take the 288 players and divide by 24 teams = 12 players per team
Take the 288 players and divide by 18 teams (which you get from
subtracting the 24 teams by 6 because you reduced the teams.)
=16 players per team
Now take the 12 players from the first calculation and compare it with the 16 players from the second calculation, so 4 more players were added to each team.
The answer is.... b) 4 more
2) Remember odd numbers are those numbers that can't be divided by two evenly, meaning you'll always have a reminder. For example take the number 81 from the problem. If you divide by 2, you will get 40.5. 40.5 is not a whole number with the .5 there, so 81 is an odd number. An easier way to identify odd numbers is to look at the number in the ones place, 81< (That's me trying to point at the ones place)
All odd numbers have either 1, 3, 5, 7, or 9 in the ones place, so look for them.
The answer is... 49 and 81.
