What is 2/3 X 4/5?

Fractions are a fundamental concept in mathematics, and understanding how to multiply them is an essential skill for everyday life and more advanced mathematical endeavors. In this blog post, we will delve into the multiplication of fractions, specifically exploring the product of 2/3 and 4/5. We will break down the process step by step, provide real-life examples, and offer practical tips to make multiplying fractions a breeze.

What is 2/3 X 4/5?

When you multiply 2/3 by 4/5, you simply multiply the numerators (2 and 4) to get 8 and multiply the denominators (3 and 5) to get 15. So, 2/3 x 4/5 equals 8/15.

Multiplying Fractions: The Basics

Before we dive into the specific problem of multiplying 2/3 by 4/5, let’s establish a fundamental understanding of how to multiply fractions. When multiplying fractions, you simply multiply the numerators (top numbers) together to get the new numerator, and you multiply the denominators (bottom numbers) together to get the new denominator. The result is a simplified fraction that represents the product of the two fractions.

Step 1: Multiplying the Numerators

In our case, we want to multiply 2/3 by 4/5. To find the new numerator, we multiply the numerators of the two fractions together: 2 x 4 = 8.

Step 2: Multiplying the Denominators

Next, we multiply the denominators together: 3 x 5 = 15.

Step 3: Simplifying the Fraction

Now, we have a new fraction, 8/15. However, it’s good practice to simplify fractions whenever possible. In this case, the numerator (8) and the denominator (15) have no common factors other than 1, so the fraction 8/15 is already in its simplest form.

Real-Life Applications

Understanding how to multiply fractions is not just a theoretical exercise; it has real-life applications that can be incredibly useful. Here are a few examples:

  1. Baking and Cooking: Recipes often require you to adjust ingredient quantities based on the number of servings you want to make. Multiplying fractions allows you to scale up or down your recipes accurately.
  2. Home Improvement: If you are working on a home improvement project that involves measurements, you may need to multiply fractions to calculate dimensions, materials needed, or costs.
  3. Finances: When dealing with money, you may need to calculate percentages, which can involve multiplying fractions. For example, calculating a discount or sales tax on an item.
  4. Probability: In probability theory, multiplying fractions is used to calculate the probability of two independent events occurring in succession.

Tips for Multiplying Fractions

While multiplying fractions is straightforward, it can be helpful to keep a few tips in mind to make the process even easier:

  1. Simplify Before Multiplying: Whenever possible, simplify the fractions before multiplying to avoid dealing with larger numbers.
  2. Use Visualization: You can visualize fractions as parts of a whole to better understand their multiplication. For example, 2/3 can be thought of as two-thirds of something, and 4/5 as four-fifths of something.
  3. Cross-Canceling: In more complex fraction multiplication problems, you can cross-cancel common factors between numerators and denominators to simplify the fractions before multiplying.
  4. Practice: Like any mathematical skill, practice makes perfect. The more you practice multiplying fractions, the more confident and efficient you will become.


Multiplying fractions, such as 2/3 by 4/5, is a valuable skill that finds applications in various aspects of our lives, from cooking and home improvement to finance and probability. By following the simple steps of multiplying the numerators and denominators, you can arrive at the correct product.

Remember to simplify the fraction when possible, and with practice, you’ll master this essential mathematical concept. Fractions may seem daunting at first, but with a little practice and understanding, they become a breeze to work with in everyday situations and more advanced mathematical endeavors.
