Question

Explain what a "seventh" means in each of the following terms:

a. Ordinal number

b. Unit fraction

Answer 1

a.) The numbers which give us the exact quantity of an object are called cardinal numbers. In other words, cardinal numbers answer “How many?”

Hence, $7^{th}$ means the position at seventh number.

b.) In math, a unit fraction can be defined as a fraction whose numerator is 1. It represents 1 shaded part of all the equal parts of the whole.

Hence, "seventh" means $\dfrac{1}{7}$
