Question

What expression represents a number one fourth as great as 10-2

Answer 1

Answer:

The expression represents

$a\geq\frac{1}{4}\times (10^{-2})$ and solution is   $a \geq 0.0025$  

Step-by-step explanation:

Given : Expression represents a number one fourth as great as $10^{-2}$

To find : What is the expression?

Solution :

Let the number be 'a'.

According to question,

A number one fourth as great as $10^{-2}$

i.e.  $a\geq \frac{1}{4}\times (10^{-2})$

Now, we solve the expression

$a \geq \frac{1}{4}\times\frac{1}{100}$

$a \geq\frac{1}{400}$

$a \geq 0.0025$

Therefore, The expression represents

$a\geq\frac{1}{4}\times (10^{-2})$ and solution is   $a \geq 0.0025$

Answer 2

Answer:

8+1/4

Step-by-step explanation:

8+1/4 because 10-2 is 8.
