Example Question #3 : Solve Word Problems Leading To Inequalities: Ccss.Math.Content.7.Ee.B.4b
Express the following as an inequality:
Bob's amount of apples (
To solve, you must convert the statement into an expression. The key work is "is". Whatever is on the left of that in the sentence will be on the left side of the expression. The same goes for the right. Thus, 
Example Question #11 : Writing Inequalities
Write the following as a mathematical inequality:
A number is less than or equal to three times the sum of another number and five
Write the following as a mathematical inequality:
A number is less than or equal to three times the sum of another number and five.
Let's begin with
"A number" let's call it x
"...is less than or equal to..."
So far we have:
Now,
"...three times..."
"...the sum of another number and five."
So, all together:
Example Question #1 : Solve Word Problems Leading To Inequalities: Ccss.Math.Content.7.Ee.B.4b
Write the inequality:
Two less than twice a number is less than two.
Break up the statement by parts. Let that number be 
Twice a number:
Two less than twice a number:
Less than two:
Combine the parts.
The answer is:
Example Question #11 : Writing Inequalities
Write the inequality: Three less than twice a number is more than three times the number.
Break up the sentence into parts. Let the number be 
Twice a number:
Three less than twice a number:
Three less than twice a number is more than:
Three times the number:
Combine the terms to form the inequality.
The answer is:
