W goes into Y: y ÷ W = Y/W times.
W goes into Y: y ÷ W = Y/W times.
if x + y = w, then x = w - y
w=x-y w+y=x
Writing W/Y, as a decimal requires information about W and Y.
x - y = w Add y to both sides: x = w + y
If you mean: m +Y = w then the value of m = w -Y
If they have no prime factors in common, the LCM of w and y is their product.
