Answer 2

To add mixed numbers like these, you can follow these steps:

Step 1: Add the whole numbers together. Step 2: Add the fractions together. Step 3: If the fraction sum is greater than or equal to 1, convert it to a mixed number.

Let's apply these steps to your problem:

1 2/3 + 6 4/15 + 8 17/45

Step 1: Add the whole numbers: 1 + 6 + 8 = 15

Step 2: Add the fractions: 2/3 + 4/15 + 17/45

To add these fractions, you need to find a common denominator. The least common denominator for 3, 15, and 45 is 45.

Now, you need to express each fraction with the common denominator:

(2/3) * (15/15) = 30/45 (4/15) * (3/3) = 12/45 (17/45) * (1/1) = 17/45

Now, add the fractions:

30/45 + 12/45 + 17/45 = (30 + 12 + 17)/45 = 59/45

Step 3: Convert the fraction to a mixed number if necessary: 59/45 is an improper fraction because the numerator (59) is greater than the denominator (45). To convert it to a mixed number, divide the numerator by the denominator:

59 ÷ 45 = 1 with a remainder of 14

So, the mixed number is 1 14/45.

Now, add the whole number from Step 1 back in:

15 + 1 14/45

So, the final result is:

16 14/45
