"The addition sentence looks like: 2/3 + 3/4 = 5/7."
This sentence is mathematically wrong.
Fractions are not added by adding the numerators
and then adding the denominators as is done in
The rules require that we find a least common denominator,
convert each fraction to that denominator, then add.
The LCM for your problem is 12
The fractions become 8/12 + 9/12
The sum then becomes 17/12 or 1 5/12
