what is the simplest form of 6/15, 15/60,and 78???????

6/15= 2/5 divide 6 and 15 by 3

15/60=1/4 divide 15 and 60 by 15
78=78 (whole number)

6/15= 2/5 divide 6 and 15 by 3

15/60=1/4 divide 15 and 60 by 15
78=78 (whole number)

To find the simplest form of a fraction, you need to simplify the numerator and denominator by finding their greatest common divisor (GCD) and dividing both with it.

1. Simplest form of 6/15:
To find the GCD of 6 and 15, start by finding the factors of each number:
- The factors of 6 are 1, 2, 3, and 6.
- The factors of 15 are 1, 3, 5, and 15.

The largest number that divides both 6 and 15 is 3. Divide both the numerator and denominator by 3:
6 ÷ 3 = 2
15 ÷ 3 = 5

Therefore, the simplest form of 6/15 is 2/5.

2. Simplest form of 15/60:
Find the GCD of 15 and 60:
- The factors of 15 are 1, 3, 5, and 15.
- The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

The largest number that divides both 15 and 60 is 15. Divide both the numerator and denominator by 15:
15 ÷ 15 = 1
60 ÷ 15 = 4

Therefore, the simplest form of 15/60 is 1/4.

3. 78 is already a whole number, so it is already in its simplest form.

In summary:
- 6/15 simplifies to 2/5.
- 15/60 simplifies to 1/4.
- 78 does not require simplification.
