Rounding a number to one decimal place means rounding it to one number after the decimal point (dot/period). The first number after the decimal point is a 4. To determine if it should be rounded up you look at the second number after the decimal with is also a 4. If it were a five or greater you would round up, but it's not so you don't.

Thus 2.447 rounded to one decimal place is 2.4
