6. 13.9 less than a number \( n \) equals 27

To solve the equation, we can rewrite it as \( n - 13.9 = 27 \). By adding 13.9 to both sides, we get \( n = 27 + 13.9 \), which simplifies to \( n = 40.9 \). So, the number we were looking for is \( 40.9 \). In the world of math, equations like this help us understand how different quantities relate to each other!
