To solve for x in the equation “x% of 75 = 90”, you can start by dividing both sides by 75, which gives you “x% = 90/75”. This fraction can be simplified to “x% = 12/10” or “x% = 1.2”. Therefore, the answer to the original question is that 90 is 120% of 75. In other words, 75 is the base, or the 100%, and 90 is 20% more than 100%, which makes it 120% of the base.
This may seem like a simple example, but understanding how to calculate percentages is a fundamental skill that can help you in many real-life situations. For example, if you are working with a budget or a sales report, you may need to calculate percentages to see how much of a certain item or category contributes to the total. By using percentages, you can also compare different quantities or values that may have different scales or units, and make meaningful comparisons.
To get a better sense of how percentages work, you can try some of these examples:
– What is 30% of 200? (Answer: 60)
– If you have a 20% discount on a $50 item, how much will you pay? (Answer: $40)
– If a student answered 80 out of 100 questions correctly on a test, what was their percentage grade? (Answer: 80%)
When working with percentages, it can be helpful to use visualization tools like proportion diagrams, pie charts, or bar graphs. These can help you see how different percentages relate to each other and to the whole, and make it easier to communicate your findings to others. You can also use spreadsheets or calculators to perform calculations quickly and accurately, and avoid rounding errors or other mistakes.

2. “Simple Math: Solving the Mystery of What Percent 90 Represents of 75”
Step 1: Convert the given numbers to fractions
The first step in understanding what percentage 90 represents of 75 is to convert these two numbers into fractions. To do this, simply divide 90 by 100 and 75 by 100. This will give you the fractions:
- 90/100
- 75/100
Step 2: Simplify the fractions
Next, we need to simplify these fractions so we can easily compare them. To simplify a fraction, we need to find the greatest common factor (GCF) of the numerator and denominator and divide both by that factor. In this case, the GCF of both fractions is 25:
- 90/100 = 9/10
- 75/100 = 3/4
Step 3: Calculate the percentage
Now that we have our fractions, we can easily calculate the percentage represented by 90 out of 75. To do this, we simply divide the numerator (9) by the denominator (10) and multiply by 100:
- (9/10) x 100 = 90%
Therefore, 90 represents 90% of 75.
Step 4: Understanding the result
What does it mean to say that 90 represents 90% of 75? Basically, it means that if we had 75 items and we took away 10% (which is 7.5), we would be left with 67.5 items. If instead, we took away 90% (which is 67.5), we would be left with only 7.5 items.
Step 5: Checking our work
We can check our work by reversing the process and calculating what percentage 75 represents of 90. Using the same steps as above, we get:
- 75/100 = 3/4
- 90/100 = 9/10
- (3/4) / (9/10) x 100 = 83.33%
This means that 75 represents 83.33% of 90, which makes sense since 75 is less than 90.
3. “Illuminating the Unknown: Discovering What Percentage of 75 Equates to 90”
To determine what percentage of 75 equates to 90, we must first understand the concept of percentages. A percentage is a way of expressing a number as a fraction of 100. In other words, it represents a certain portion of a whole.
To solve the problem at hand, we can set up a proportion. We know that 90 is some percentage of 75. Let’s call that percentage “x”. Therefore, we can write:
