Question

What do you add to 3 7/8 to make 7

Answer 1

To make it to 7 you have to convert mixed fraction to improper fraction and then to decimal..

3 7/8 = 45 / 8 = 5.625
after this you can subtract 7 from 5.625
i.e. 7 - 5.625 = 1.375

So if you add 1.375 with 5.625 you will get 7
i.e. 1.375 + 5.625 = 7

Answer 2

If you would like to know how much do you have to add to 3 7/8 to get 7, you can calculate this using the following steps:

3 7/8 = 31/8

7 - 3 7/8 = 7 - 31/8 = 56/8 - 31/8 = 25/8 = 3 1/8

The correct result is 3 1/8 or 25/8.
