Answer:

find a common denominator so the two fractions can be added.
which gives # 17/12# or 1 + #5/12#

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 xx 2/3 + 3/3 xx 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.
