How are a common denominator and a common multiple alike and different?

Answers

The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15
A common denominator and common multiple are alike because they both go on the bottom portion of the fraction and in order to get the common denominator you need to find the common multiple of numbers.

They are different because they have different purposes and the common denominator stays the same and the common multiple is supposed to change both or one number.

It would be B. 2/5
Count the tick marks by 10th so at the dot it's -4/10 which simplify to -2/5. And the absolute value of -2/5 is 2/5.

- The Yankees won 90 of their 162 games lastseason. What percent of the games did they
win?​

Answers

Final answer:

The Yankees won approximately 55.56% of their games last season. We calculated this by dividing the number of games they won (90) by the total number of games played (162) and then multiplying the result by 100.

Explanation:

To calculate the percentage of games won by the Yankees, we divide the number of games they won by the total number of games played, and then multiply the result by 100. This can be represented mathematically by the formula: (Number of wins / Total number of games)*100.

So in this case, they won 90 games out of a total of 162. Plugging those figures into our formula gives us: (90/162)*100 which is approximately 55.56%. Therefore, the Yankees won approximately 55.56% of their games last season.

there are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign any remaining players to make some of the teams have 10 players.how many teams of 10 players. how many teams of 9 players

Answers

The number of nine-players team= 21 teams.

The number of ten-players team= 5 teams.

Step-by-step explanation:

step 1: The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.

step 2: The coach first makes a 9 players team= 239-9= 230 members

In this stage, the number of 9 players-team is one.

step 3: The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.

step 4: Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)

Therefore, 230-180= 50 players are remaining.

In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.

The number of 10 players-team= 50 players/10= 5 teams with 10-players.
