Math Problem Statement

what integer should replace N so that the values below are in ascending order? 85%, n/10,0.92

Solution

To determine the value of NN so that the values 85%, N10\frac{N}{10}, and 0.92 are in ascending order, we need to compare all values after converting them into the same format. Let's express all values as decimals:

  • 85%85\% as a decimal is 0.850.85.
  • N10\frac{N}{10} is 0.1N0.1N.
  • 0.920.92 is already a decimal.

Now, let's arrange these values in ascending order:

0.850.1N0.920.85 \leq 0.1N \leq 0.92

To find NN, we'll solve these two inequalities:

  1. 0.850.1N0.85 \leq 0.1N: N0.850.1=8.5N \geq \frac{0.85}{0.1} = 8.5 Since NN is an integer, N9N \geq 9.

  2. 0.1N0.920.1N \leq 0.92: N0.920.1=9.2N \leq \frac{0.92}{0.1} = 9.2 Since NN is an integer, N9N \leq 9.

From these inequalities, N=9N = 9 is the only integer solution.

So, N=9N = 9 should replace NN so that the values are in ascending order.
