What is 2/4 in simplest form
Gennadij [26K]
2/4 in simplest form:

First, to find the simplest form of a fraction, you'll need to find the greatest common factor (GCF). To do this, we can list the factors of 2 and 4 and find the first common one.

Factors of 2: 1, 2
Factors of 4: 1, 2, 4

Since 2 is our first common factor, it is our GCF.

Second, we can now take our GCF (2) and divide it with our numerator and denominator. We will get a new numerator and denominator.

2 \div 2 = 1  \\  4 \div 2 = 2

Answer in fraction form: \fbox {1/2}
Answer in decimal form: \fbox {0.5}
