To add the fractions 3/20 + 1/2, we need to find a common denominator.
The denominator of the first fraction, 3/20, is already 20.
The denominator of the second fraction, 1/2, is 2. To make it the same as the first fraction's denominator, we need to multiply both the numerator and denominator by 10. This gives us 10/20.
Now that both fractions have the same denominator, we can simply add the numerators:
3/20 + 10/20 = 13/20
Therefore, the sum of 3/20 + 1/2 is 13/20.
To add the fractions 3/20 and 1/2, follow these steps:
Step 1: Find a common denominator:
The denominators in this case are 20 and 2. Since 20 is divisible by 2, the common denominator is 20.
Step 2: Convert the fractions to have the common denominator:
To convert 3/20, we multiply the numerator and denominator by 1 to get:
3/20 = 3 * 1 / 20 * 1 = 3/20
To convert 1/2, we multiply the numerator and denominator by 10 to get:
1/2 = 1 * 10 / 2 * 10 = 10/20
Step 3: Add the converted fractions:
3/20 + 10/20 = (3 + 10) / 20 = 13/20
Therefore, the sum of the fractions 3/20 and 1/2 is 13/20.
To add fractions, you need to have a common denominator. In this case, the common denominator is 20. The first fraction, 3/20, already has the denominator of 20, so you don't need to make any changes to it. The second fraction, 1/2, needs to be converted to have a denominator of 20.
To convert 1/2 to have a denominator of 20, you need to multiply both the numerator and denominator by a number that will result in 20 as the denominator. In this case, you need to multiply both by 10.
1/2 * (10/10) = 10/20
Now that both fractions have the same denominator, you can add them together:
3/20 + 10/20 = (3 + 10)/20 = 13/20
So, the sum of the fractions 3/20 + 1/2 is 13/20.
