I have to write in simplest form. Are all my answers in simplest form also?

All are right! :-)

Yes.

Thank you!

You're welcome.

55/80 in simplest form

To check if the given equations are correct, you can perform the subtraction operation and verify if the results match the ones given. Here's how you can do it:

1. 5 - 3 4/7 = To subtract mixed numbers, first convert both numbers into improper fractions. 5 can be written as 35/7. Now we have 35/7 - 3 4/7. The whole number 3 can be converted to 21/7. Adding that to 4/7 gives us 25/7. Now subtracting 25/7 from 35/7, we get 10/7, which is equal to 1 3/7. Therefore, the equation is correct: 5 - 3 4/7 = 1 3/7.

2. 8 - 2 3/8 = Convert 8 to 64/8. Now we have 64/8 - 2 3/8. The whole number 2 can be converted to 16/8. Adding that to 3/8 gives us 19/8. Now subtracting 19/8 from 64/8, we get 45/8, which is equal to 5 5/8. Therefore, the equation is correct: 8 - 2 3/8 = 5 5/8.

3. 6 1/3 - 2 2/3 = Convert 6 to 18/3. Now we have 18/3 - 2 2/3. The whole number 2 can be converted to 6/3. Adding that to 2/3 gives us 8/3. Now subtracting 8/3 from 18/3, we get 10/3, which is equal to 3 1/3. Therefore, the equation is incorrect: 6 1/3 - 2 2/3 ≠ 3 2/3.

4. 7 1/3 - 4 1/2 = Convert 7 to 21/3. Now we have 21/3 - 4 1/2. The whole number 4 can be converted to 8/2. Adding that to 1/2 gives us 9/2. Now subtracting 9/2 from 21/3, we get 27/6, which simplifies to 4 1/2. Therefore, the equation is incorrect: 7 1/3 - 4 1/2 ≠ 2 5/6.

5. 11 2/7 - 5 2/3 = Convert 11 to 77/7. Now we have 77/7 - 5 2/3. The whole number 5 can be converted to 15/3. Adding that to 2/3 gives us 17/3. Now subtracting 17/3 from 77/7, we get 130/21, which is equal to 6 4/21. Therefore, the equation is incorrect: 11 2/7 - 5 2/3 ≠ 5 13/21.

6. 12 1/6 - 4 3/8 = Convert 12 to 72/6. Now we have 72/6 - 4 3/8. The whole number 4 can be converted to 32/8. Adding that to 3/8 gives us 35/8. Now subtracting 35/8 from 72/6, we get 37/24, which is equal to 1 13/24. Therefore, the equation is incorrect: 12 1/6 - 4 3/8 ≠ 7 19/24.
