Answer:

7 1/15

Step-by-step explanation:

Rewriting our equation with parts separated

=3+2/5+3+4/6

Solving the whole number parts

3+3=6

Solving the fraction parts

2/5+4/6=?

Find the LCD of 2/5 and 4/6 and rewrite to solve with the equivalent fractions.

LCD = 30

12/30+20/30=32/30

Reducing the fraction part, 32/30,

32/30=16/15

Simplifying the fraction part, 16/15,

16/15=1 1/15

Combining the whole and fraction parts

6+1+1/15=7 1/15

Answer:

6 32/30 or 7 2/30 or 7 1/15
