Question

What is the sum and difference of 5 upon 7 and 4 upon 3

Answer 1

there sum is43upon21. and there difference is-13upon21.

Answer 2

5 upon 7 is the same as 5/7. 4 upon 3 is equivalent to 4/3.

To find the sum of 5/7 and 4/3, we need to first change their denominators to 21. Multiply 5 and 7 with 3, and also multiply 4 and 3 with 7.

5/7 + 4/3 = 15/21 + 28/21

Now, add the 15 and 28.

15/21 + 28/21 = 43/21

Hence, the sum of the fractions are 43/21 (or 2.048).

Then, we find the difference between the fractions: 5/7 - 4/3

Change the fractions to what we did when calculating the sum.

5/7 - 4/3 = 15/21 - 28/21

Now we subtract 28 from 15.

15/21 - 28/21 = -13/21

*The negative sign is not needed when showing the difference.

Therefore, the difference between the fractions is 13/21 (or 0.619).
