Solving Unit Rate Word Problems Effectively

In this video, Mr. J explains how to solve unit rate word problems through three examples: calculating the price of gas per gallon, determining the miles a car travels per hour, and finding out how many cookies are baked per batch. He emphasizes the importance of setting up fractional ratios correctly and ensuring the order matches the question's requirements. The video concludes with a reminder to focus on the question's order rather than the original problem's order.

What is the first step in solving a unit rate problem?

• Multiply the values

• Set up a fractional ratio

• Subtract the total cost

• Divide the numerator

How do you determine the order of terms in a fractional ratio?

• Always quantity first

• Always cost first

• Based on the question asked

• Random order

What is the unit rate of gas if 4 gallons cost $12.80?

• $3.20 per gallon

• $3.00 per gallon

• $4.00 per gallon

• $2.80 per gallon

What does a denominator of 1 represent in unit rate calculations?

• Per unit quantity

• None of the above

• Total quantity

• Initial quantity

Why is it important to follow the order specified in the question when setting up ratios?

• To avoid division

• To ensure accuracy in the answer

• To make it easier to solve

• To use fewer numbers

What is the correct setup for a ratio when asked 'how many miles did the car travel per hour'?

• Miles over hours

• Hours over miles

• Hours divided by miles

• Miles times hours

How many miles per hour did the car travel if it covered 480 miles in 8 hours?

• 100 miles per hour

• 60 miles per hour

• 80 miles per hour

• 40 miles per hour

What is the unit rate if a car travels 480 miles in 8 hours?

• 60 miles per hour

• 75 miles per hour

• 65 miles per hour

• 55 miles per hour

If a baker made 180 cookies in 3 batches, how many cookies were made per batch?

• 120 cookies

• 60 cookies

• 90 cookies

• 30 cookies

What mathematical operation is used to convert a ratio to a unit rate?

• Addition

• Multiplication
