Question

The table shows the heights that four people parachute from an airplane. What is the range of the heights? Write your answer as a decimal or fraction in simplest form.

Answer 1

The answer is 1.55

Step-by-step 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

`2`
`(2)/(3)`: 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).

`(2)/(1)` ×
`(2)/(3)` =
`(4)/(3) = 1.333`

`(49)/(20)` : This number is a fraction to simplify it divide the nominator by the denominator:

`(49)/(20)`
`= 2.45`

`2 (3)/(5)`: Write the integer as a fraction and then simplify

`(2)/(1)` ×
`(3)/(5) = (6)/(5) = 1.2`

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
