Answer:

#1 712/1365#

Explanation:

Change to improper fractions first, then do the division.
DO the addition of the fractions last.

#1 29/35 div 1 11/15 + 7/15#

=#64/35 color(red)(div 26/15) +7/15#

=#64/35 color(red)(xx15/26) + 7/15 " "larr " cancel"#

=#cancel64^32/cancel35^7 xxcancel15^3/cancel26^13 + 7/15#

=#96/91 +7/15 = 1 5/91 + 7/15#

=#1 (5xx15 +7xx91)/(91xx15)#

=#1 (75+637)/1365#

=#1 712/1365#

What awful numbers to work with!
