Completely depends on Size of the Kidney stone, if the size is around 1-3mm then it easily dissolve if you are drinking the right amount of after but if the Stone is around 5-6mm then you need to consult experienced urologist, since it can take around 6 weeks, but you need to take proper medication. Consult these Urologists to know or for Questions:

According to the BMI Chart you are underweight. Your BMI is 16.5. A healthy BMI is 20-22 or at your height 95-100 pounds.

This should not be taken as medical advice but only a general guide. Person who are athletic or weightlifters may have different results.

The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value. However, there is some debate about where on the BMI scale the dividing lines between categories should be placed.[2] Commonly accepted BMI ranges are underweight: under 18.5, normal weight: 18.5 to 25, overweight: 25 to 30, obese: over 30.

The question is worded in such a way to be open to misunderstanding. I feel it could mean Norah must spread her stone at the rate of 2/3 of a ton per square yard across 4 square yards and the total is sought.
It could also be saying that Norah has 2/3 of a ton to be divided equally across 4 square yards and is seeking the amount of stone each square yard needs.

In the former case it is a matter of multiplying the vulgar fraction by four and in the latter case the answer could be approached by considering the total amount of stone given is four times the answer that is required and so would be given by dividing 2/3 by 4/1 or more simply by multiplying by 1/4 and not forgetting to cancel the resulting fraction down to the lowest common denominator.

A better way for practical purposes would be to convert 2/3 of a ton into pounds and then divide by four. A workman required to do the work would not be messing around with fractions but would be working in pounds and tons or if using Imperial measure it would be pounds, stones, hundredweight and tons.

Obviously some wires shorting out, probably at the rear of the truck where gravel stones have pounded them Or, if you have a trailer plug on it, that would be a good place to look.

If you have an aftermarket trailer plug on it, remove it, or unhook the wires. They are shorting out. If you don't have a trailer plug, then check the wires at the back of your truck. They must be pounded from stones,and are shorting out.

You must have a bare wire at the back of your truck that's shorting out where gravel stones have pounded the outside coating off. If you have an after market trailer plug on there, you might want to check that out too. The connections to your main wires from the trailer plug, are never done properly, and always cause problems somewhere.
