Question

Ariel incorrectly says that 2 and 5/8 is the same as 2.58. a. Convert 2 and 5/8 to a decimal. B. What was Ariel’s likely error?

Answer 1

2 and 5/8 as a decimal is 2.4

Ariel's likely error was that she assumed that 5/8 and .58 are the same.

Answer 2

a.2.625

b.Ariel takes the value of
`(5)/(8)=0.58` .It is error of Ariel.

Explanation:

We are given that Ariel incorrectly says values of
`2(5)/(8)` and 2,58 are same.

We have to convert
`2(5)/(8)` into a decimal and we have to find the Ariel's error.

`2(5)/(8)=2+(5)/(8)`

`2(5)/(8)=2+0.625=2.625`

The value of
`2(5)/(8)` =2.625 not 2.58

Ariel consider that value of
`(5)/(8)=0.58` but actually value of
`(5)/(8)=0.625`.

Hence, Ariel takes value of
`(5)/(8)`=0.58 in place of 0.625.
