What is comparing quantities

Comparing Quantities, Ratios, and Percentages

Ratios and Proportions

1. What's a Ratio?:
2. A ratio helps you compare two things of the same type. We use ':' to show a ratio, like 3:4, which is read as "3 is to 4."
3. Equivalent Ratios: Sometimes, different ratios can mean the same thing. If they do, we call them equivalent.
4. Proportion: When two ratios are equal, they are in proportion. We use the symbol '::' to show this.

For example, if 3:4::6:8, then 3 times 8 should be equal to 4 times 6.

Percentages

1. What's a Percentage?:
2. A percentage is a fraction out of 100. We use the symbol '%'.
3. Changing Forms: You can turn fractions or decimals into percentages by multiplying by 100. And you can turn percentages back into fractions or decimals by dividing by 100.

Profit and Loss

1. Cost Price (CP): The money spent to buy something.
2. Selling Price (SP): The money earned by selling it.
3. Profit or Gain: If SP is more than CP.
4. Loss: If CP is more than SP.

Simple Interest

1. What's Interest?:
2. When you borrow money, you pay back more than you borrowed. The extra money is called interest.
3. Principal: The money you borrow.
4. Simple Interest Formula: The formula to find out the interest is (Principal x Rate x Time)/100.

Changing Forms and Uses

1. Percentages for Real-life: We can use percentages to understand real-life things like how many students in a class have a cold.
2. From Ratios to Percentages: Sometimes we use ratios to make percentages easier to understand.

General Ideas

1. Same Units: To compare things, they should be in the same units, like all in meters or all in litres.

comparing quantities formula

Ratios and Proportions

• Ratio: $\text{Ratio}=\frac{\text{Part 1}}{\text{Part 2}}$
• Proportion: $�:�=�:�$ (read as $�$ is to $�$ as $�$ is to $�$)

Percentages

1. Percentage to Fraction: $\text{Percentage}=\frac{\text{Number}}{100}$
2. Fraction to Percentage: $\text{Percentage}=\text{Fraction}\times 100$

Profit and Loss

1. Profit: $\text{Profit}=\text{Selling Price}-\text{Cost Price}$
2. Loss: $\text{Loss}=\text{Cost Price}-\text{Selling Price}$
3. Profit Percentage: $\text{Profit \%}=\left(\frac{\text{Profit}}{\text{Cost Price}}\right)\times 100$
4. Loss Percentage: $\text{Loss \%}=\left(\frac{\text{Loss}}{\text{Cost Price}}\right)\times 100$

Simple Interest

• Simple Interest: $\text{Simple Interest}=\frac{\text{Principal}\times \text{Rate}\times \text{Time}}{100}$

Compound Interest

• Compound Interest: $�=�\times {(1+\frac{�}{100})}^{�}$, where $�$ is the amount after $�$ periods, $�$ is the principal amount, $�$ is the rate, and $�$ is the time in the same units as the rate.
