Question

If 0.4 < x > 45%, which of the following could be the value of x?​

Answer 1

5/10

Explanation:

So you can split this into two inequalities, x > 0.4 and x > 45%. First you can change the second one to decimal form, so x > 0.45. Because 0.45 is already greater than 0.4, you can just ignore the second inequality. (If x is greater than 0.45 it will automatically be greater than 0.4 so it doesn't matter).

From the 4 options you gave, 5/10, or 0.5, is the only one that is greater than 0.45.

Answer 2

0.41, 0.42, 0.43, 0.44

Explanation:

Convert the percent to a decimal:

0.4 < x > 0.45

Now, the variable x has to be any number between 0.4 and 0.45, which include:

0.41, 0.42, 0.43, 0.44
