The answer is 1.55
Explanation:
The he first step to find the range is to make all the values either fractions or decimal/integer numbers. Below I show the process to make all the numbers decimals/integers
Height in miles
2.75: This number is decimal because of this it does not have to be modified
[tex]2[/tex] [tex]\frac{2}{3}[/tex]: 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).
[tex]\frac{2}{1}[/tex] ×[tex]\frac{2}{3}[/tex] = [tex]\frac{4}{3} = 1.333[/tex]
[tex]\frac{49}{20}[/tex] : This number is a fraction to simplify it divide the nominator by the denominator:
[tex]\frac{49}{20}[/tex][tex]= 2.45[/tex]
[tex]2 \frac{3}{5}[/tex]: Write the integer as a fraction and then simplify
[tex]\frac{2}{1}[/tex] ×[tex]\frac{3}{5} = \frac{6}{5} = 1.2[/tex]
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
