It is 1.
Writing W/Y, as a decimal requires information about W and Y.
Anything over itself is 1.
.25 and y
Two decimal numbers, X and Y, are equal if X - Y = 0.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
We could answer that if we knew the value of 'y'.
Yes.
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.
4
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.
