Round 4.432 to the nearest tenth.
Slav-nsk [51]

Answer:

4.4

Step-by-step explanation:

The tenth place in this number is 4.<u>4</u>32, so that should be the last digit.

Now, we need to know wether to round up or down. That is determined by the digit that comes after it. <em>If that digit, here it is the hundredth, is 0-4, it rounds down, if it is 5-9, it rounds up</em>. Our next digit is <em>3</em>, which goes into the first category, <em>so the number rounds down</em>, so the tenth remains the same. That leaves us with 4.4.
