Final answer:
Numbers in the range 1-7 can be written as ratios of two integers. The number 7.52 can be expressed as 752/100.
Step-by-step explanation:
All numbers in the given range (1-7) can be represented as ratios of two integers (a fraction) because they are all rational numbers. For example, the number 1 can be written as 1/1, 2 can be written as 2/1, and so on.
The number 7.52 can also be expressed as a ratio of two integers. It can be written as 752/100, since the decimal part can be converted to a fraction. However, the given answer choices do not match this representation.
