What is 70 Percent of 30?

What is 70 percent of 30?

Answer: 70 percent of 30 is 21. Alternatively, we can say that 21 is equivalent to 70% of 30.

Solution for What is 70 percent of 30:

n = 70 percent of 30

n = 70 % * 30

n = \frac{70}{100} * 30

n = \frac{70 * 30}{100}

n = \frac{2100}{100}

n = 21

Now we have 70% of 30 = 21. Alternatively, we can express it as 70 percent of 30 equals 21.

The step-by-step process for finding what is 70 percent of 30:

The mathematical calculation of 70% of 30 can be broken down as follows:

70 percent * 30
Convert this into an equation: (70 / 100) * 30
Simplify the equation further: (70 * 30) / 100
Carry out the calculation: 2100 / 100
The final answer is: 21

Thus, we conclude that 70% of 30 is 21.

Explanation for What is 70% of 30:

Step 1: **70 percent * 30**

Think of percent as parts out of 100. So, when we say 70 percent, it's like having 70 parts out of a total of 100. What we want to do now is find out what those 70 parts would be if our total was 30 instead of 100.

Step 2: **(70 / 100) * 30**

This is like dividing our 70 parts into 100. It's as if we have 100 pieces of candy and we only want 70 of those pieces. That gives us 0.70 or 70 hundredths. Now we multiply those 70 parts (or 0.70) by 30 to find out what 70% of 30 would be.

Step 3: **(70 * 30) / 100**

This is an alternative calculation. Instead of doing it in two steps like we did before, we can also do it in one step. First, we multiply 70 (our 70 parts) by 30 (our total amount), and then we divide that by 100.

Step 4: 2100 / 100

The previous step gave us 2100. But remember we were pretending our total was 100? Now we have to divide by 100 to get back to the number for our real total, which is 30. That's why we divide 2100 by 100.

Step 5: 21

Finally, after dividing 2100 by 100, we arrive at the answer: 21. Hence, we can definitively say that 70% of 30 equals 21.
