114.425<114.58 because 425<580.
The easiest way to reach this solution is to look at the numbers. Everything before the decimal point is the same, but the first digit after the place holder differs, one is four tenths and the other is 5 tenths. 4 is less than 5 making the first statement the correct one!
So your answer would be 7 because if you divide 21÷3 your answer would be 7.
Yes that is correct to my knowledge
