Calculate 30% of 90: A Hands-On Math Problem

Calculate 30 % of 90:

To solve this problem, we will determine 30% of 90 using the percentage formula. Here's how we'll do it:

• Step 1: Identify the necessary formula for the calculation.
• Step 2: Substitute the values into the formula and compute.
• Step 3: Verify the result and match it with the answer choices.

Now, let's proceed through these steps:

Step 1: The formula for calculating a percentage of a number is given as:
$\text{Percentage Value} = \left( \frac{x}{100} \right) \times \text{Total}$

Step 2: Substitute the given values into the formula.
Here, $x = 30$ and $\text{Total} = 90$. Thus, the formula becomes:
$\text{Percentage Value} = \left( \frac{30}{100} \right) \times 90$.

Step 3: Compute the expression.
First, calculate $\frac{30}{100} = 0.3$.
Then multiply by 90:
$0.3 \times 90 = 27$.

Therefore, 30% of 90 is $27$.
