One tenth is 0.1. Therefore, the answer has to be 2.x. Since 4 is less than 5, the 2 remains the same. The answer is 2.2.
2.2 because if its was 2.25 you would round to 2.3 but because it is 2.24 you round down giving 2.2
When rounding 2.24 to the nearest tenth, we look at the digit in the hundredths place, which is 4. Since 4 is less than 5, we round down and keep the tenths digit as 2. Therefore, the answer is 2.2.
