The quotient of 45 and r is 45/r.
A quotient is the result of a division between more than one number. For example 10/5 = 2. The quotient is 2.
In an algebraic equation, 45 and r are known as variables. The whole equation is known as an algebraic equation. In our example let us call the quotient x. The equation would then be x = 45/r. If we were to give 'r' the value of 5, for example. Our equation would be:x = 45/5. Therefore, in this case, the quotient is 2.
