Questions & Answers

Q: What is a ratio and how is it used?

A ratio is a way of comparing two or more sets of quantities. It can be expressed as a fraction and is used to understand the relationship between different amounts.

Q: Why is it important to have the same units when using ratios?

Having the same units is crucial in ratios because it allows for accurate comparison. Different units would result in an incorrect ratio.

Q: How can ratios be simplified?

Ratios can be simplified by finding a number that evenly divides both values. By dividing both parts of the ratio by this number, the ratio is reduced to its simplest form.

Q: How can ratios be used to divide quantities?

Ratios can be used to divide quantities into a given proportion. By determining the total number of parts in the ratio and dividing the total amount by that number, the value of each part can be found. Multiplying this value by the respective part of the ratio gives the amount each person receives.

Summary & Key Takeaways

• Ratios are a method of comparing two or more sets of quantities, such as the amount of cordial to water in a glass.

• Measurements need to have the same units when using ratios. If they do not, conversion is necessary.

• Ratios can be simplified by finding a number that goes into both values and dividing them. Simplification reduces the ratio to its simplest form.

• Ratios can be used to divide quantities into a given proportion, ensuring each part receives its fair share.
