Скачать или смотреть Reciprocal of 1 1/2 (One and One-Half)

To find the reciprocal for a number we need to change 1 1/2 to an improper fraction. When we do that we end up with 3/2. This is equal to 1 1/2.

To find the reciprocal we flip the numerator and denominator. That gives us 2/3 as the reciprocal for 3/2.

The reciprocal is also called the multiplicative inverse. So we can check to see if we have the correct reciprocal for 3/2 (or 1 1/2) by multiplying it by its reciprocal. This should be equal to 1.

3/2 x 2/3 = 6/6 = 1

Note that the reciprocal of 3/2 (or 1 1/2) is not equal to 2/3. They are different numbers.

For whole numbers, (2, 3 …) we can consider these to be divided by one. For example, 2 can be considered to be 2/1. This makes it possible to find the reciprocal by flipping the numerator and denominator.
