LCM & GCF word problems

What are we looking for: GCF or LCM? Once you've decided solve the problem.

1) Sapphire and Abe are shelving books at a public library. Sapphire shelves 5 books at a time, whereas Abe shelves 6 at a time. If they end up shelving the same number of books, what is the smallest number of books each could have shelved? 

2) For a dinner party, Abraham is creating individual servings of starters. He has 9 carrot sticks and 18 celery sticks. If he wants each serving to be identical, with no food left over, what is the greatest number of servings Abraham can create?

Kim before Kanye

 In 2011, reality television star Kim Kardashian and basketball player Kris Humphries got married. After their very short-lived marriage (72 days), Kim decided to donate twice the value of all of her wedding gifts to charity. All of the wedding gifts’ worth was estimated at $100,000, so she donated $200,000 to the Dream Foundation. We can write a rational fraction to represent the amount she donated to her net worth. Looking at the link given below, her net worth is approximately $35 million. Let’s write this as a rational number and simplify. Our fraction represents the fraction of the money that was given in relation to how much she is worth.

Net worth is the sum total of what you own minus what you owe.

Order of Operations

Margot volunteers at a local bird sanctuary. She just spent two weeks on vacation, so on her first day back she is talking to her supervisor about what she has missed. When Margot left, there were 256 birds. In her absence, 3 birds have each given birth to 5 baby birds, 2 birds were released into the wild and 3 new injured birds were brought in. How can Margot write an expression to figure out the new sanctuary population?

An equation is a number sentence that describes two values that are equal to each other. The values are separated by the "equals" sign, e.g. 3 + 4 = 7. In this case, 3 + 4 and 7 are equal entities. Sometimes you will be given an incomplete equation, which you have to "solve" in order to make both sides equal.

An expression is a number sentence without an equals sign. It can be simplified and/or evaluated, but it cannot be "solved".

Expressions can involve more than one operation, so it is important to know which operation to do first. The order of operations tells you the correct order for completing operations within an expression.

Order of Operations
P - parentheses
E - exponents
MD - multiplication or division, in order from left to right

AS - addition or subtraction, in order from left to right

Now, let's return to Margot and her bountiful birds.

Margot needs to write and evaluate an expression to see how the original population of 256 has changed since 3 birds each gave birth to 5 baby birds, 2 birds were released, and 3 injured birds were brought in.

First, identify the important information in the problem.

256 birds to start

3 birds have 5 babies each

2 birds released

3 birds added

Next, write this as an expression.

256+3×5−2+3

Then, use order of operations to evaluate the expression.

256+3×5−2+3256+15−2+3271−2+3269+3272Multiply 3×5Add 256+15Subtract 271−2Add 269+3===-

The answer is 272.

Margot’s sanctuary now has 272 birds
