Solving One-Step Inequalities with Multiplication and Division

Mrs. Yaud teaches students how to solve inequalities using multiplication and division. She demonstrates the effects of adding, subtracting, multiplying, and dividing by positive and negative numbers on a number line. The lesson emphasizes the importance of flipping inequality signs when multiplying or dividing by negative numbers. Students are guided through solving various inequality problems, with a focus on understanding the core concept of inequality sign changes.

What happens to the inequality when both sides are multiplied by a positive number?

• The inequality becomes an equation.

• The inequality remains the same.

• The inequality reverses.

• The inequality becomes undefined.

In the context of inequalities, what does it mean when a number line shows one number is less than another?

• The first number is positioned to the right of the second on the number line.

• The first number is positioned to the left of the second on the number line.

• The position of numbers does not indicate their value.

• Both numbers are equal.

In a real-world scenario, if the total number of two items is known to be at most a certain number, how would you express this as an inequality?

• Using an equal sign.

• Using a 'less than or equal to' sign.

• Using a 'greater than or equal to' sign.

• Using a 'not equal to' sign.

If the number of one item is known to be twice the number of another, how would you set up an equation to find the quantity of the first item?

• Subtract two from the quantity of the second item.

• Add two to the quantity of the second item.

• Divide the quantity of the second item by two.

• Multiply the quantity of the second item by two.
