Carlotta rounded a number to the nearest tenth and got 4.5. When she rounded it to the nearest whole number, she got 5. Which of these could be the number she rounded?

4.5 ≤x<4.55

Step-by-step explanation:

for whole number

It has to be 4.5 or greater to round to 5 on the low end

It has to be less than 5.5 to round to 5 on the high end

for tenths

If has to be 4.45 or greater to round to 4.5 on the low end

It has to be less than 4.55 to round to 4.5

We take the more restrictive limits to define the number

The number must be between

4.5 ≤x<4.55
