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

Answer:

a.2.625

b.Ariel takes the value of $\frac{5}{8}=0.58$ .It is error of Ariel.

Step-by-step explanation:

We are given that Ariel incorrectly  says values of $2\frac{5}{8}$ and 2,58 are same.

We have to convert $2\frac{5}{8}$ into a decimal and we have to find the Ariel's error.

$2\frac{5}{8}=2+\frac{5}{8}$

$2\frac{5}{8}=2+0.625=2.625$

The value of  $2\frac{5}{8}$ =2.625 not 2.58

Ariel consider that value of $\frac{5}{8}=0.58$ but actually value of $\frac{5}{8}=0.625$.

Hence,  Ariel takes value of $\frac{5}{8}$=0.58 in place of 0.625.
