Well, isn't that a lovely number! When we round 79.38 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is equal to or greater than 5, we round up the tenths place to 79.4. Just like adding a happy little touch to a painting, rounding can make numbers more pleasing to the eye.
