One car is 3.9 meters long the other is 6%shorter

How long is second car?
What is the formula I use for questions involving %

3.7

How would you know to subtract 0.06 from 1?

To find the length of the second car, we first need to calculate how much shorter it is compared to the first car.

Let's start by determining the amount that the second car is shorter by.

Given that the first car is 3.9 meters long and the second car is 6% shorter, we can find the amount by which the second car is shorter as follows:

Step 1: Calculate the percentage by which the car is shorter:
6% of the first car's length = (6/100) * 3.9

Step 2: Subtract the percentage from the first car's length to find the reduced length of the second car:
Length of the second car = Length of the first car - Percentage reduction
Length of the second car = 3.9 - ((6/100) * 3.9)

Now, let's simplify the equation to find the length of the second car:

Length of the second car = 3.9 - (0.06 * 3.9)
Length of the second car = 3.9 - 0.234
Length of the second car = 3.666 meters

Therefore, the second car is approximately 3.666 meters long.

As for the formula to use in questions involving percentages, you'll generally follow these steps:

1. Determine the base value (in this case, the length of the first car).
2. Calculate the percentage of the base value (in this case, 6% of the first car's length).
3. Subtract the calculated percentage from the base value to find the reduced value (in this case, the length of the second car).

Keep in mind that the formula might vary depending on the specific context of the question, but this general formula should suffice for most percentage-related calculations.

Change the percent to a decimal.

6% = 0.06

In this situation subtract 0.06 from 1.

Then multiply.

0.94 * 3.9 = ?
