Height in miles
2.75: This number is decimal because of this it does not have to be modified
: This number includes a rational number and a fraction to make this just one number write the first number as a fraction, multiply, and then divide the top number by the low number (denominator).

: This number is a fraction to simplify it divide the nominator by the denominator:
: Write the integer as a fraction and then simplify
×
Now, from these values, the higher one is 2.75 and the lowest is 1.2, to find the range find the difference between these two numbers 2.75 - 1.2 = 1.55
