Studdy Solution

STEP 1

Assumptions1. We are asked to evaluate two expressions 0÷90 \div9 and 80\frac{8}{0}. . Division by zero is undefined in mathematics.

STEP 2

First, let's evaluate the first expression 0÷90 \div9.

STEP 3

In mathematics, any number divided by9 is equivalent to multiplying that number by the reciprocal of9, which is 19\frac{1}{9}. So, 0÷90 \div9 can be written as 0×190 \times \frac{1}{9}.

STEP 4

Now, calculate the value of 0×190 \times \frac{1}{9}.
0×19=00 \times \frac{1}{9} =0

STEP 5

So, 0÷9=00 \div9 =0.

STEP 6

Now, let's evaluate the second expression 80\frac{8}{0}.

STEP 7

In mathematics, division by zero is undefined. Therefore, 0\frac{}{0} is undefined.
The evaluated expressions are0÷9=00=Undefined\begin{array}{r} 0 \div9=0\\\frac{}{0}= Undefined\end{array}
