Calculate the exact value of 3 1/5 - 2/3 ÷ 2 4/5

1/3

Step-by-step explanation:

311/105   or   2  101/105

Step-by-step explanation:

1. Expand the fractions

16/5 -  2/3 ÷ 14/5

2. Do the division first. For the division part, you would have to flip 14/5, which will be the reciprocal of 14/5, 5/14. You would also want to change the ÷ to ×.

16/5 - 2/3 × 5/14

16/5 - 5/21

3. Then you do the subtraction part. Make sure you factor them and make their bases into the same numbers.

336/105 - 25/105

311/105

4. Since 311 is a prime number, so we can't simplify further, unless you want it like this:

2  101/105
