Rewrite the expression with a positive rational exponent. Simplify, if possible.100-1/2

Sagot :

[tex]100-\frac{1}{2}[/tex]

We need that the 100 has a 2 in the denominator. To do this, we can multiply on top and bottom by 2:

[tex]100\cdot\frac{2}{2}=\frac{200}{2}[/tex]

Now, we can make the subtraction:

[tex]\frac{200}{2}-\frac{1}{2}=\frac{199}{2}[/tex]

The answer is 199/2
