Answer 3

To add the two mixed numbers 18 15/20 and 3 11/20, you can follow these steps:

Step 1: Add the whole numbers together. 18 + 3 = 21

Step 2: Add the fractions together. To do this, you first need to find a common denominator, which in this case is 20.

15/20 + 11/20 = (15 + 11)/20 = 26/20

Step 3: Simplify the fraction if necessary. In this case, the fraction can be simplified because both 26 and 20 are divisible by 2.

26/20 = (26 ÷ 2)/(20 ÷ 2) = 13/10

Step 4: Add the whole number from step 1 to the fraction from step 3. 21 + 13/10

Now, you can add the whole number and the fraction. To add a whole number and a fraction, you can convert the whole number to an equivalent fraction with the same denominator as the fraction (in this case, 10).

21 = 21/10

Now you can add the fractions:

21/10 + 13/10 = (21 + 13)/10 = 34/10

Step 5: Simplify the fraction if necessary. 34/10 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(34 ÷ 2)/(10 ÷ 2) = 17/5

So, the result is 17/5, which is an improper fraction. If you prefer a mixed number, you can express it as:

3 2/5

Therefore, 18 15/20 + 3 11/20 = 3 2/5.
