Adding Fractions: 1/20 + 1/30
When it comes to adding fractions, it's essential to have a common denominator. In this case, we want to add 1/20 and 1/30.
Step 1: Find the Least Common Multiple (LCM)
To add these fractions, we need to find the least common multiple (LCM) of 20 and 30. The LCM of 20 and 30 is 60.
Step 2: Convert the Fractions
Now, we need to convert both fractions to have a denominator of 60:
- 1/20 = 3/60 (multiply numerator and denominator by 3)
- 1/30 = 2/60 (multiply numerator and denominator by 2)
Step 3: Add the Fractions
Now that we have the same denominator, we can add the fractions:
3/60 + 2/60 = 5/60
Simplifying the Fraction
We can simplify the fraction 5/60 by dividing both numerator and denominator by their greatest common divisor, which is 5:
5 ÷ 5 = 1 60 ÷ 5 = 12
