A number line going from 0 to 1. There are 6 equal spaces between 0 and 1. The line contains 0, A, B, blank, C, D, 1.
TiliK225 [7]

Answer:

The number line is divided by 6ths.

Step-by-step explanation:

There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.

-11.3 is rational or irrational ? explain? 0.083 and 2.1371938 to please if its not much to ask?
zloy xaker [14]
Ignore the - sign for now.   11.3   =   11.3        113
                                                         -------  = ----------
                                                             1             10

Since this is the ratio of two integers, 11.3 is rational.  So is 11.3.

                                                                             83
If you really mean   <span>0.083, this is rational:  it is ---------
                                                                            1000

If y ou meant </span><span>0.083333333 ... , that's also rational:  1/12 is equivalent.</span>

Paul bought 2.25 meters of wood to make 5 shelves of equal length . What is the length of each shelf ? show your work on a picec
LiRa [457]

Answer:

Length of each shelf is 0.45 meters

Step-by-step explanation:

Given

Total\ Length = 2.25\ meters

Shelves = 5

Required

Determine the length of each shelf

This is calculated by dividing the total length by number of shelves as thus:

Length = Total\ Length/Number\ of\ Shelf

Length = 2.25m /5

Length = 0.45m

Hence;

<em>Length of each shelf is 0.45 meters</em>
