Calculation of Fractions

To calculate the expression one whole and two-thirds plus one whole and one-fifteenth plus four-fifths, we can break it down step by step.

First, let's convert all the fractions to a common denominator. The common denominator for 3, 15, and 5 is 15.

- Two-thirds can be written as 10/15. - One-fifteenth remains as 1/15. - Four-fifths can be written as 12/15.

Now, we can add the whole numbers to the fractions:

- One whole and two-thirds is equal to 1 + 10/15. - One whole and one-fifteenth is equal to 1 + 1/15. - Four-fifths remains as 4/5.

Calculation Steps

1. One whole and two-thirds: - 1 + 10/15 = 15/15 + 10/15 = 25/15

2. One whole and one-fifteenth: - 1 + 1/15 = 15/15 + 1/15 = 16/15

3. Four-fifths: - 4/5

Now, we can add these together: 25/15 + 16/15 + 4/5

Final Calculation

To add these fractions, we need to find a common denominator, which is 15 in this case: 25/15 + 16/15 + 12/15 = (25 + 16 + 12)/15 = 53/15

So, one whole and two-thirds plus one whole and one-fifteenth plus four-fifths equals 53/15.

This calculation is based on the standard rules for adding fractions and whole numbers.
