Explanation:

by bringing all terms to the same fractions (with the same denominator).

so, we have

7

5/7

that means we want to bring both numbers to .../7 form.

7 means 7 whole units.

1 whole unit has now many parts ?

if we aim for 2 parts, that makes 1 whole unit 2/2.

if we aim for 3 parts, 1 whole unit is 3/3.

...

you see, 3/3 = 1/1 = 1.

that is the whole trick.

so, we are looking for 7 parts, and 1 whole unit is 7/7.

now we have 7 whole units.

how many parts are those ?

well, 7 × 7/7 = 49/7

there we go.

we have

7 - 5/7 = 49/7 - 5/7 = 44/7 = 42/7 + 2/7 = 6 2/7
