Hey there!

The answer is B.


- LEARN WHY -

Step 1: Defenition of irrational numbers.

A rational number is a number that can be written as a fraction, and therefore an irrational number is a <u>number that cannot be written as a fraction</u>


Step 2: Apply the knowledge

-22 as a fraction would be -22/1

3/8 is already a fraction

8.5 as a fraction would be 8 1/2


Only 7.832... cannot be written as a fraction.

Hence, number B is irrational


~Hope this helps you!

A rectangle is divided into equal squares. One row covers 1/8 of the whole rectangle. There are 3 squares in each row. How many
LenaWriter [7]

Answer:

There are 24 squares in the entire rectangle

Step-by-step explanation:

Trom the problem, we are given that one row covers 1/8 of the entire rectangle.

We are also told that this one row, contains three squares.

In other words, what this means is that three squares cover 1/8 of the entire rectangle.

The question is now if three squares cover only 1/8 of the rectangle, how many squares cover the whole rectangle.

In fraction, we can represent a whole using 1/1

We can set up a simple relation to this effect.

3 squares give 1/8 of the rectangle

x squares give 1/1 of the rectangle

cross multiplying, we have

x = 3 ÷(1/8) = 24

Therefore, there are 24 squares in the entire rectangle
