4/6 is not in the simplest form.
What is a fraction?
In mathematics, a fraction is a number that represents a portion of a whole. There are two parts to it: a numerator and a denominator. The numerator is the total number of pieces that make up the whole, whereas the denominator is the number of equal parts that make up the whole.
How to solve this problem?
Here, to find the simplest formed fraction, we have to check if the gcd (greatest common divisor) of the numerator and the denominator is 1.
Now, in 10/21, the gcd of 10 and 21 is 1. So, 10/21 is the simplest form.
In 6/7, the gcd of 6 and 7 is 1. So, 6/7 is the simplest form.
In 3/5, the gcd of 3 and 5 is 1. So, 3/5 is the simplest form.
In 4/6, the gcd of 4 and 6 is 2. So, 4/6 is not the simplest form.
Therefore, 4/6 is not in the simplest form.
