5 Simple Steps To Solve 9/10 Divided By 3/5

Division of fractions can seem intimidating at first, but with a basic understanding of how they work and a few simple steps, you'll be able to tackle even complex problems like 9/10 divided by 3/5. Here's how to master this arithmetic operation with ease.

Understanding Fraction Division

Before diving into the specifics of 9/10 divided by 3/5, let's get a grip on what fraction division means. Dividing by a fraction is essentially multiplying by its reciprocal. Here's a quick recap:

• Reciprocal: The reciprocal of a fraction is what you get by swapping the numerator and the denominator. For instance, the reciprocal of 3/5 is 5/3.

• Dividing Fractions: If you need to divide two fractions a/b by c/d, you multiply a/b by the reciprocal of c/d, which gives you (a/b) * (d/c).

Steps to Divide 9/10 by 3/5

Step 1: Write the Problem Out

Begin by laying out the division problem:

9/10 ÷ 3/5

Step 2: Find the Reciprocal of the Divisor

The divisor here is 3/5, so its reciprocal would be 5/3.

Step 3: Multiply by the Reciprocal

Now, multiply 9/10 by 5/3:

(9/10) * (5/3) = (9 * 5) / (10 * 3)

Step 4: Simplify the Multiplication

Calculate the numerators and denominators separately:

(9 * 5) = 45
(10 * 3) = 30

So, you now have:

45/30

Step 5: Simplify the Fraction

Lastly, simplify 45/30 by finding the greatest common divisor (GCD) of 45 and 30, which is 15.

45/30 = (45 ÷ 15) / (30 ÷ 15) = 3/2

So, 9/10 divided by 3/5 is 3/2, which can be expressed as 1 1/2 or 1.5 if converted to a mixed number or decimal respectively.

Practical Examples and Scenarios

Example 1: Baking

Imagine you're baking a cake that requires 9/10 cup of flour. However, you've only got a measuring cup divided into units of 3/5 cup. Here's how you'd apply the division:

• You need 9/10 cup of flour, which is (9/10) / (3/5) = 3/2 cups.
• So, you'd use the 3/5 cup twice plus half of the 3/5 cup to get the 9/10 cup.

Example 2: Fractions in Measurements

If you're working on a construction project and need to divide a 9/10 meter piece of wood into sections of 3/5 meter:

• You'll need to determine how many 3/5 meters fit into 9/10 meters:
  • 9/10 ÷ 3/5 = 3/2
• This means you could cut the wood into 1 1/2 sections of 3/5 meters.

Tips and Tricks for Fraction Division

Understand the Concept of Reciprocals

• Remember that the reciprocal of a fraction involves swapping the numerator with the denominator. This is a fundamental step in fraction division.

Use Visual Aids

• Drawing diagrams or using models like pie charts can help visualize the division process. Seeing fractions in graphical form can make it more intuitive.

Practice with Simple Numbers

• Start with easier fractions like 1/2 ÷ 1/4 or 3/4 ÷ 2/3. Master these, then move to more complex fractions.

Know Your GCD

• The greatest common divisor (GCD) is your key to simplifying fractions quickly. If you're adept at finding GCDs, you can simplify almost any fraction instantly.

Avoid Common Mistakes

• Dividing by One: Dividing by 1 (or 1/1) doesn't change the value of the fraction you're dividing.

• Order Matters: When dividing fractions, remember to divide the first fraction by the reciprocal of the second, not the other way around.

Troubleshooting Tips

• Simplification: Always check if you can simplify fractions before and after the division to make the problem easier.

• Negative Fractions: If working with negative fractions, keep in mind that the rules for multiplication and division don't change; you just need to account for the signs at the end.

Final Thoughts

Dividing fractions, as demonstrated by 9/10 divided by 3/5, is not as complex as it might appear. By understanding the basic principles and following the simple steps outlined, you can solve these problems efficiently.

Remember to:

• Master the concept of reciprocals.
• Simplify where possible.
• Utilize visual aids and practice with smaller fractions first.
