Answer:
find a common denominator so the two fractions can be added.
which gives
17/12
or 1 + 5/12
Step-by-step explanation:
Two terms can only be added if there are the same.
2/3
and
3/4
are not the same. The two terms can be made the same by finding a common denominator 3x 4 = 12 so 12 will work as a common denominator.
multiply both the top and the bottom by the factor to make 12
4/4×2/3+3/3×3/4
This gives
8/12+9/12 The two terms can now be added giving
17/12 This is an improper fraction that can be rewritten as
1×5/12 This is how to evaluate two fractions with different denominators.
