Dividing gives: #77/91#

Adding gives # 8 2/21#

Explanation:

It seems there is a problem with the question:

If it is meant to be division: #3 2/3 div 4 3/7#

Change to improper fractions: #11/3 div 31/7#

Multiply by the reciprocal: #11/3 xx7/31#

Nothing cancels. Multiply across: #77/91#

Fractions which will give a recurring decimal are better left in fraction form which is accurate and does not entail any rounding off.

If it is meant to be addition: #3 2/3 + 4 3/7#

Add the whole numbers then find a common denominator and make equivalent fractions:

#3 2/3 + 4 3/7=7 (14+9)/21#

#= 7 23/21 = 7+1 2/21#

#8 2/21#
