You've described only one ratio. The ratio is (7pencils) / (13 erasers) = 0.5385 pencil per eraser (rounded)
5- two by using the lead point of each pencil and 3 by using one lead point and the eraser end.
For my ACT, I brought two calculators (make sure not a TI89 for they are not allowed), a water bottle, snacks, sharpened #2 pencils, a big eraser, and my brain.
In order to do this you first need to go to the Swap Meet and buy some pencils, eraser..etc. Don't 4get the papel! Nos vemos compa! :)
If you only have 184 pencils then only 184 kids will get both a pencil and an eraser, even if you have more erasers than that.

Erasers (commonly knowns a rubbers) come in all shapes, sizes and weights. Probably the smallest is the eraser that fits on the end of some makes of pencils.
The plural of eraser is erasers.

It is called a pen eraser.
Erasers pick up graphite particles, thus removing them from the surface of the paper. Basically, the molecules in erasers are 'stickier' than the paper, so when the eraser is rubbed onto the pencil mark, the graphite sticks to the eraser preferentially over the paper. Some erasers damage the top layer of the paper and remove it as well. Erasers attached to pencils absorb the graphite particles and leave a residue which needs to be brushed away. This type of eraser can remove the surface of the paper. Soft vinyl erasers are softer than the erasers attached to pencils, but are otherwise similar.
The eraser is made out of rubber.
Pencils, paper, erasers, rubber bands, etc. could be described in several ways. They are most likely to be called office supplies, but they could be called desk supplies, school supplies, writing supplies, and expendibles.
no, not at all. I have the pencils where you have to push out and put back in other end, and the eraser is the worst eraser I have ever encountered in my life.
simple - eraser collector!
It is not possible to answer as there are different kinds and styles of erasers. We need to know how much one eraser weighs to find the weight of 1000 erasers.
