Question

Which inequality is true? o 8/5 < 9/10. o 1 > 6/5. o 5/2 < 2 1/2. o 8/4 < 5/1

Answer 1

The first inequality is false:

$\frac{8}{5}<\frac{9}{10}$

Mainly because 9/10 is less than 1, and 8/5 is greater than 1.

The second inequality is false:

$1>\frac{6}{5}$

Because 6/5 is greater than 1.

The third inequality is false:

$\frac{5}{2}<2\frac{1}{2}$

Because these numbers are equal to 2.5.

The fourth inequality is true:$\frac{8}{4}<\frac{5}{1}$

Because 8/4 is equal to 2, which is less than 5.
