Yes, a number in a ratio must be a whole number.
Simple whole number ratio implies that ratio of the elements in a compound is a whole number i.e. the ratio of elements bear whole number. For example in Cu2O, Cu and O combine in a simple whole number ratio of 2:1.
No, not all whole numbers are 25, but 25 is a whole number.
25 is already a whole number.
As a whole number, you can write 25 percent as 25%. As a part of a whole number, you'd write 25% of it as .25% or one quarter -- 1/4, of the whole number.
Every whole number can be expressed as the quotient or ratio of other whole numbers, and whole numbers ARE integers.
Due to the property of uniqueness, the only whole number that equals 25 is 25 itself!
It is the ratio of one whole number to another whole number, which may be expressed as a fraction. The ratio (or fraction) may be simplified by dividing both numbers by the greatest common factor.
25 IS a whole number: you need do nothing.
25 is, itself, a whole number.
-- Any number that can be written as the ratio of two whole numbers is a rational number.-- Any whole number can be written as the ratio of that number to ' 1 ', so it's rational.
