Finding Unit Rates and Situations with Fractions

This video tutorial explains how to find unit rates and solve problems involving fractions. It begins with an introduction to unit rates, followed by a detailed explanation of dividing fractions and using reciprocals. The tutorial then presents a practical problem involving two individuals, Ann and Brian, at a track practice, where their walking rates are calculated and compared. The video concludes with a summary of the key concepts covered, emphasizing the importance of understanding unit rates and fractions in problem-solving.

What is a unit rate?

• A rate that compares two different quantities.

• A rate that compares a quantity to one unit of another quantity.

• A rate that compares two similar quantities.

• A rate that is always greater than one.

How do you divide fractions?

• Add the fractions and then divide.

• Subtract the fractions and then divide.

• Multiply the numerators and denominators directly.

• Multiply by the reciprocal of the divisor.
