Add the following fractions: 7/20 + 3/5
To add these fractions, we need to find a common denominator. The denominators in this case are 20 and 5. The least common multiple of 20 and 5 is 20, so we can use that as the common denominator.
Next, we need to convert the fractions to have the same denominator.
For the fraction 7/20, the numerator stays the same and the denominator becomes 20.
For the fraction 3/5, we need to multiply both the numerator and denominator by 4 to get a denominator of 20. This gives us (3x4)/(5x4) = 12/20.
Now that the fractions have the same denominator, we can add them together:
7/20 + 12/20 = (7 + 12)/20 = 19/20.
Therefore, the sum of 7/20 + 3/5 is 19/20.
