Cross-Canceling and Fraction Operations

The video tutorial explains how to solve a one-step equation involving a mixed number. It begins by converting the mixed number into an improper fraction. The instructor then demonstrates solving the equation by isolating the variable using reciprocal multiplication. A cross-cancelling technique is introduced to simplify fractions, ensuring the final answer is in its simplest form.

What is a one-step equation?

• An equation that requires only one operation to solve

• An equation that requires two operations to solve

• An equation with multiple variables

• An equation that cannot be solved

What is a mixed number?

• A number with a whole part and a fractional part

• A number that is always negative

• A number with a decimal

• A number that is always positive

How do you convert a mixed number to an improper fraction?

• Multiply the denominator by the whole number and add the numerator

• Divide the numerator by the whole number

• Add the whole number to the numerator

• Subtract the numerator from the denominator

What is the first step in solving the equation 14/5x = 10?

• Add 5 to both sides

• Multiply both sides by 5

• Isolate the variable X

• Subtract 10 from both sides

What is a reciprocal?

• The same fraction flipped upside down

• A fraction that is equal to zero

• A fraction with a numerator of 1

• A fraction with a denominator of 1

Why do we use reciprocals in solving equations?

• To add more steps to the solution

• To make the equation more complex

• To eliminate the variable

• To simplify the equation by making the coefficient of the variable 1

What does cross-canceling mean?

• Multiplying fractions directly

• Dividing fractions by each other

• Simplifying fractions by canceling common factors across the numerator and denominator

• Adding fractions together

When can you cross-cancel fractions?

• When one number is in the numerator and the other is in the denominator

• When both numbers are in the denominator

• When the fractions are equal

• When both numbers are in the numerator

What is the final answer to the equation after solving 14/5x = 10?

• x = 14/10

• x = 10/14

• x = 7/25

• x = 25/7

What is the purpose of simplifying fractions before multiplying?

• To make the equation more complex

• To make the numbers larger

• To change the value of the fractions

• To avoid simplifying the answer later
