8,8+9,4=18,2

Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Add the whole numbers: 3 + 2 + 8 + 9 = 22.

Step 2: Add the fractions separately. To add fractions, they need to have the same denominator. In this case, the denominators are already the same, so we can add the numerators directly.

7/10 + 9/10 = (7 + 9)/10 = 16/10.

Step 3: Simplify the fraction 16/10. Since the numerator is greater than the denominator, we can simplify it by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 2.

16/10 = (16 ÷ 2)/(10 ÷ 2) = 8/5.

Step 4: Add the fractions with the same denominator:

8/5 + 4/5 = (8 + 4)/5 = 12/5.

Now, let's put it all together:

3 + 7/10 + 2 + 9/10 + 8 + 4/5 + 9 + 2/5 = 22 + 16/10 + 12/5.

Simplifying the fractions:

22 + 16/10 + 12/5 = 22 + 8/5 + 12/5.

Adding the fractions:

22 + 8/5 + 12/5 = (22 + 8 + 12)/5 = 42/5.

Therefore, the final answer is 42/5.

Please note that the answer has been calculated based on the given expression.
