Understanding Ratios and Their Applications

The video tutorial covers the concept of ratios, starting with simple examples using cakes and biscuits. It then explores how ratios are applied in recipes, demonstrating how to scale ingredients for different serving sizes. The tutorial further explains the use of ratios in factory production, showing how recipes are scaled up for mass production. Finally, it discusses the application of ratios in distributing funds for charity projects, providing a practical example of dividing money between different causes.

If the ratio of cakes to biscuits is 3 to 2, what happens to the ratio if you add one more cake?

• The ratio becomes 4 to 3

• The ratio becomes 3 to 3

• The ratio remains 3 to 2

• The ratio becomes 4 to 2

In a recipe, if you need to double the ingredients for 8 people, what should you do?

• Add twice the amount of each ingredient

• Add half the amount of each ingredient

• Add the same amount of each ingredient

• Add three times the amount of each ingredient

How do you calculate the amount of ingredients needed for 30 people if a recipe is for 4 people?

• Divide each ingredient by 4, then multiply by 30

• Multiply each ingredient by 30

• Multiply each ingredient by 4

• Divide each ingredient by 30, then multiply by 4

When scaling up a recipe for factory production, why is it easier to convert measurements to kilograms?

• Because it reduces the number of ingredients needed

• Because it increases the precision of measurements

• Because it simplifies calculations with large numbers

• Because kilograms are smaller units

If a factory needs to produce 4000 jars of sauce, how do you determine the amount of each ingredient needed?

• Divide the amount for one jar by 4000

• Subtract 4000 grams from each ingredient

• Add 4000 grams to each ingredient

• Multiply the amount for one jar by 4000

Comic Relief allocates funds in a 1:2 ratio between the UK and Africa. What does this mean?

• For every pound spent in Africa, two pounds are spent in the UK

• For every pound spent in the UK, two pounds are spent in Africa

• Funds are equally divided between the UK and Africa

• All funds are spent in Africa

How do you calculate the amount of money each region receives if the total is divided in a 1:2 ratio?

• Divide the total by 4 and allocate one part to the UK and three parts to Africa

• Divide the total by 2 and allocate equally

• Divide the total by 3 and allocate one part to the UK and two parts to Africa

• Divide the total by 3 and allocate two parts to the UK and one part to Africa

In a ratio problem, what is the first step to find out how much each share receives?

• Multiply the total by the number of shares

• Add the numbers in the ratio to find the total number of shares

• Divide the total by the largest number in the ratio

• Subtract the number of shares from the total

What mistake did the narrator make in the ratio problem involving Comic Relief?

• Added the wrong numbers in the ratio

• Multiplied the total by the wrong number of shares

• Subtracted the wrong numbers in the ratio

• Divided the total by the wrong number of shares

Why is it important to add all numbers in a ratio before dividing the total?

• To ensure the total is divided equally

• To make the calculation faster

• To avoid using a calculator

• To find the correct number of shares
