To add fractions, we need to have a common denominator. In this case, the common denominator is 20.

We rewrite the fractions with the common denominator:

7/20 + 3/5 = 7/20 + (3/5) * (4/4)
= 7/20 + 12/20

Now, we can add the fractions:

7/20 + 12/20 = (7 + 12)/20
= 19/20

Therefore, 7/20 + 3/5 = 19/20.

To add fractions, you need to have a common denominator. In this case, the least common denominator is 20.

To make the denominators 20, you need to multiply the numerator and denominator of the first fraction by 5 and the numerator and denominator of the second fraction by 4.

So, the fractions become:

(7/20) * (5/5) + (3/5) * (4/4)

This simplifies to:

35/100 + 12/100

Now that the denominators are the same, you can add the numerators:

35 + 12 = 47

So, the sum of the fractions 7/20 + 3/5 is 47/100.

To add fractions, you need to have a common denominator. The common denominator is the least common multiple (LCM) of the denominators.

To find the LCM of 20 and 5, you can multiply the two numbers together and then divide by their greatest common divisor (GCD). In this case, the GCD of 20 and 5 is 5.

LCM(20, 5) = (20 * 5) / 5 = 20

Now that we have the common denominator of 20, we can rewrite the fractions with that denominator:

7/20 + 3/5 = (7 * 1)/(20 * 1) + (3 * 4)/(5 * 4)
= 7/20 + 12/20

Now that the fractions have the same denominator, we can simply add the numerators:

7/20 + 12/20 = 19/20

So, the sum of 7/20 and 3/5 is 19/20.
