what is the snswer to this sum
a x 4 = d
a * 4 = d
a = d/4?

By the way, your equation seems to indicate a product rather than a sum.
To find the value of "a" when "d" is given, we need to isolate "a" in the equation.
We can do that by dividing both sides of the equation by 4, because dividing by 4 is the inverse operation of multiplying by 4. This will give us:
(a x 4) / 4 = d / 4
On the left side, the 4s cancel out, leaving us with:
a = d / 4
So, the answer to the equation "a x 4 = d" is "a = d / 4".
