If a=b, what is the numerical value of the quantity a/b?

The numeric value is 1.

Explanation:

We have given that the “a” equal to “b” which means we can replace the “a” with “b” or we can replace the “b” with “a”.  

The given condition or quantity = a/b.

Now it is required to find the numeric value of a/b.  

To find the numeric value we first replace the “b” with “a” and then divide the values. Since we know that if the numeration and denominators are the same then after dividing the value, the resulting value will be 1.

The numerical value = a/b = a/a = 1
