Classify each number as rational or irrational. 0.167 2/9 π 225√

A number is rational if we can write that number as a fraction.

A number is irrational if we can not write as a fraction. This means if a number has non repeating and non terminating decimal values then it is an irrational number.

Now let us look at our given numbers one by one.

We can write as . Hence it is a rational number.

This number is already written as fraction. It is a rational number.

We can not write as a fraction because the equivalent   decimal values of   are  non repeating and non terminating. Therefore   is an irrational number. Remember that is just an approximation for . It isn't the actual value of .

is equivalent to 15. We can write 15 as a fraction like . Therefore is a rational number.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
