Final answer:
Two-thirds of a number is represented as 2/3 multiplied by that number (2/3 × n), showing a part of the whole and is used in calculations involving fractions and proportions.
Step-by-step explanation:
When we talk about two-thirds of a number, we're dealing with fractions and proportion. To understand what this term looks like, we can consider other fractions we're familiar with. Knowing that half of something is the same as multiplying it by 0.5, we can understand that two-thirds involves multiplying a number by 2/3. Therefore, if we have a number, let's call it n, two-thirds of it would be represented mathematically as 2/3 × n. This expresses a part of that number n and is particularly useful in solving problems involving ratios and proportions.
