Diego compared the difference for 1/10 - 1/10 and 100/100 - 10/100. He said the difference both equal 9/10. Is Diego correct? Explain

Respuesta :

Answer:

Hence, Diego was wrong with his calculations. The difference of both are not equal to [tex]\dfrac{9}{10}[/tex].

Step-by-step explanation:

No, Diego is not correct.

He went wrong in his calculations.

since,

the difference of [tex]\dfrac{1}{10}[/tex] and  [tex]\dfrac{1}{10}[/tex] is 0 (As both the numbers are same so their difference will be zero)

but the difference of [tex]\dfrac{100}{100}[/tex] and [tex]\dfrac{10}{100}[/tex] is solved as:

As [tex]\dfrac{100}{100}=1[/tex]

and [tex]\dfrac{10}{100}=\dfrac{1}{10}[/tex]

and now the difference is:  [tex]1-\dfrac{1}{10}=\dfrac{10-1}{10}=\dfrac{9}{10}[/tex]

Hence the difference for both the operations is not same.
