MathAlgebra Least Common Multiple: Easy
A multiple is the product of two integers. To �nd the multiples of a certain number, multiply that number by every integer, starting with 1.
Least common multiple (LCM) is the smallest common multiple of two or more numbers.From the example above, the LCM of 2 and 3 is 6.LCM can be found by listing the multiples and looking for the smallest common one in the lists.
Common multiples are numbers that share one or more of the same multiples.Example: Multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. Multiples of 3 are 3, 6, 9, 12, 15, and so on.6 and 12 appear in these lists, so they are common multiples of 2 and 3.
Example: The multiples of 2 are 2, 4, 6, 8, 10, and so on.
Multiples of 4 = 4, 8, 12, 16, 20, ... Multiples of 5 = 5, 10, 15, 20, 25, ...
Circle the common multiples of the pair of numbers, then answer the questions.

Measuring liquids in graduated cylinders is often tricky because the liquid surface is curved. This curved surface is called the meniscus and occurs because of the strong attractive force between the glass and water.
Procedure:1. Measure the amount of liquid in the graduated cylinders below. When you measure make sure to measure the amount using the bottom of the meniscus for any liquid volume measuring tool. 2. Record the measurement and label your units in mL on the line below each graduated cylinder.

you to think about math and angles.
Turn the ship’s wheel according to the angle measurements

2 is a prime number and divides into 18 evenly 36 times.
18 can be divided by 2, leaving 9.
9 can be divided by 3, leaving 3. Now we have all prime numbers.
Example
Once you find the prime factors of the second number, see which numbers they have in common. Circle and multiply them to get your GCF. If there are no prime factors in common, then the GCF is 1.

Simplify the following fractions. Show your work.
Now that you’ve got the hang of it, look closely at the following fractions. They do not simplify very well, but they are very close to a simplifiable fraction. For example, 51/100 cannot be simplified, but we know that 50/100 = 1/2. So, 50/100 can be approximated to 1/2. Be sure to show your work.

MathAlgebra Least Common Multiple: Easy
A multiple is the product of two integers. To �nd the multiples of a certain number, multiply that number by every integer, starting with 1.
Least common multiple (LCM) is the smallest common multiple of two or more numbers.From the example above, the LCM of 2 and 3 is 6.LCM can be found by listing the multiples and looking for the smallest common one in the lists.
Common multiples are numbers that share one or more of the same multiples.Example: Multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. Multiples of 3 are 3, 6, 9, 12, 15, and so on.6 and 12 appear in these lists, so they are common multiples of 2 and 3.
Example: The multiples of 2 are 2, 4, 6, 8, 10, and so on.
Multiples of 4 = 4, 8, 12, 16, 20, ... Multiples of 5 = 5, 10, 15, 20, 25, ...
Circle the common multiples of the pair of numbers, then answer the questions.

you to think about math and angles.
Turn the ship’s wheel according to the angle measurements
given. See the examples below. With each new turn,
indicate the ship’s new direction by drawing a line towards
it. Turn clockwise if the angle is positive, counterclockwise
if it is negative. Use a ruler to help you draw straight lines.

2 is a prime number and divides into 18 evenly 36 times.
18 can be divided by 2, leaving 9.
9 can be divided by 3, leaving 3. Now we have all prime numbers.
Example
Once you find the prime factors of the second number, see which numbers they have in common. Circle and multiply them to get your GCF. If there are no prime factors in common, then the GCF is 1.

Angle SteeringAngle SteeringSteering a ship requires practice and precision. It also requires you to think about math and angles.
Turn the ship’s wheel according to the angle measurements given. See the examples below. With each new turn, indicate the ship’s new direction by drawing a line towards it. Turn clockwise if the angle is positive, counterclockwise if it is negative. Use a ruler to help you draw straight lines.

Simplify the following fractions. Show your work.
Now that you’ve got the hang of it, look closely at the following fractions. They do not simplify very well, but they are very close to a simplifiable fraction. For example, 51/100 cannot be simplified, but we know that 50/100 = 1/2. So, 50/100 can be approximated to 1/2. Be sure to show your work.
