Unitary Method and Rate Concepts

The video tutorial explains how to compare different quantities using rates and introduces the unitary method as a tool for simplifying calculations. It provides a detailed example of calculating the cost per kilo and extends the method to solve percentage problems. The tutorial concludes with a review and tips for simplifying complex problems by breaking them into smaller steps.

What is a rate in the context of comparing two different quantities?

• A comparison of two different quantities

• A unit of weight

• A type of currency

• A measure of speed

What is the first step in using the unitary method to find the cost of 5 kilos?

• Divide the total cost by 5

• Multiply the total cost by 5

• Find the cost of 1 kilo

• Calculate the cost of 10 kilos

How do you calculate the cost per kilo using the unitary method?

• Multiply the total cost by the number of kilos

• Subtract the number of kilos from the total cost

• Divide the total cost by the number of kilos

• Add the total cost to the number of kilos

What is the purpose of dividing both sides by 8 in the unitary method example?

• To convert the units

• To find the cost of 1 kilo

• To find the total cost

• To simplify the calculation

In the percentage problem example, what is the first step to find the total cost?

• Multiply the deposit by 100

• Divide the deposit by 15

• Add 15% to the deposit

• Subtract 15% from the deposit

What is the final step in calculating the total cost from a percentage deposit using the unitary method?

• Subtract the 1% value from the deposit

• Add the 1% value to the deposit

• Divide the 1% value by 100

• Multiply the 1% value by 100

Why is it sometimes easier to add an extra step in the unitary method?

• It reduces the number of steps

• It increases accuracy

• It simplifies the problem

• It makes the calculation faster

What is the benefit of using the unitary method in complex problems?

• It provides an exact answer

• It breaks down the problem into smaller steps

• It increases the complexity of the problem

• It eliminates the need for calculations

How can the unitary method be applied to percentage problems?

• By finding the value of 1% first

• By converting percentages to decimals

• By ignoring the percentage

• By multiplying percentages directly

What is the main idea behind the unitary method?

• To calculate the total cost directly

• To focus on a single unit and build from there

• To use complex formulas

• To avoid using ratios
